Reading .csv Files & Empty List Elements

I have an application allowing users to upload .csv files for
import into a database.
The issue is however, that in some cases every column in the
csv file will be populated, and in others, not.
As ColdFusion ignores empty list elements I cannot accurately
import data based on it's column numbers.
I'm curious how others get around this issue.

Yes, most list functions ignore empty elements. If you are
using CF8, try the listToArray function. It has a new attribute
includeEmptyElements.
Otherwise, there are several solutions. I listed a few of
them in this thread. Though there are others. You should google
something like:
ColdFusion csv Files Empty List Elements to see other
options and the +/- of each.

Question about reading csv file into internal table

Some one (thanks those nice guys!) in this forum have suggested me to use FM KCD_CSV_FILE_TO_INTERN_CONVERT to read csv file into internal table. However, it can be used to read a local file only.
I would like to ask how can I read a CSV file into internal table from files in application server?
I can't simply use SPLIT as there may be comma in the content. e.g.
"abc","aaa,ab",10,"bbc"
My expected output:
abc
aaa,ab
10
bbb
Thanks again for your help.

Hi Gundam,
Try this code. I have made a custom parser to read the details in the record and split them accordingly. I have also tested them with your provided test cases and it work fine.

Hi All,
I am a new Bee in code and started learning code, I have stared with Console application and need your advice and suggestion.
I want to write a code which read the input from the CSV file and display the output in console application combination of first name and lastname append with the name of the collage in village
The example of CSV file is

using (var rd = new StreamReader("filename.csv"))
while (!rd.EndOfStream)
var splits = rd.ReadLine().Split(';');
column1.Add(splits[0]);
column2.Add(splits[1]);
// print column1
Console.WriteLine("Column 1:");
foreach (var element in column1)
Console.WriteLine(element);
// print column2
Console.WriteLine("Column 2:");
foreach (var element in column2)
Console.WriteLine(element);

Help reading .csv file into an arraylist

i need to read a csv file into an arraylist and then print the arraylist to the screen.
using:
try {

ok, so do i need to write a file carsclass.java or is the line:
ArrayList<CarsClass> carsClass = new ArrayList<CarsClass>(" write all fields");
going to define my carsclass objects? how do i write my fields for each of the 7 categories?
i believe i can easily add to and print the arraylist, but i'm confused how to go about creating this arraylist in the first place. do i just create carclass.java and save them all as strings? i guess my question is mainly how should i structure this? any suggestions/help is appreciated.

String.split uses regular expressions.Ahh yeah ummm (slaps forehead) I'd forgotten that... so maybe StringTokeniser is more accessible for noob's. Sorry.
Anyway... if all you want/need to so is store a bunch of String field values then how about using an array of String's instead of individual fields... maybe something like:
forums\Car.java
* Car Data Transfer Object. All fields are final, making objects of this class
* thread safe(r).
* @author keith
package forums;
import krc.utilz.stringz.Arrayz;
public class Car
// class attributes                       // variables //isn't actually wrong, it's just not quit right.
private final String[] fields;            // final means values are write once, read many times, which is thread safe(r).
   * Initialises the new Cars fields to the given fields array.
   * @param fields - an array of any (reasonable) length
public Car(String[] fields) {             // no need to comment a constructor as a constructor.
    this.fields = fields;                   // much better to provide javadoc comments explaining
}                                         // what the method does and how to use it.
   * Returns this Car's fields as one long string.
public String toString() {                // It's actually GOOD to be a lazy programmer.
    return Arrayz.join(", ", this.fields); // I have reused my Arrayz.join in several projects.
                                            // I think you can use Array.toString (new in 1.6) instead.
krc\utilz\stringz\Arrayz.java
package krc.utilz.stringz;
import java.util.List;
import java.util.ArrayList;
public class Arrayz
    * returns true if the given value is in the args list, else false.
    * @param value - the value to seek
    * @param args... - variable number of String arguments to look in
public static boolean in(String value, String... args) {
    for(String a : args) if(value.equals(a)) return true;
    return false;
    * append the elements of array into one string, seperated by FS
    * @param a - an array of strings to join together
    * @param FS - Field Seperator string, optional default=" "
    * @example
    * String[] array = {"Bob","The","Builder"};
    * System.out.println(join(array);
    * --> Bob The Builder
    * System.out.println("String[] array = {\""+join(array, "\",\"")+"\"};");
    * --> String[] array = {"Bob","The","Builder"};
public static String join(String FS, String[]... arrays) {
    StringBuffer sb = new StringBuffer();
    for (String[] array : arrays)
      sb.append(join(array, FS));
    return(sb.toString());
public static String join(String[] array) {
    return(join(array, " "));
public static String join(String[] a, String FS) {
    if (a==null) return null;
    if (a.length==0) return "";
    StringBuffer sb = new StringBuffer(a[0]);
    for (int i=1; i<a.length; i++) {
      sb.append(FS+a);
return sb.toString();
* append all the elements of the given arrays into one big array
* @param String[]... arrays - to be concatenated
* @return String[] - one big array
public static String[] concatenate(String[]... arrays) {
List<String> list = new ArrayList<String>();
for(String[] array : arrays) {
for(String item : array) {
list.add(item);
return(list.toArray(new String[0]));
I guess that Arrayz class might be a bit beyond you at the moment so don't worry too much if you can't understand the code... there are no nasty surprises in it... just cut and paste the code, change the package name, and use it (for now).

Read CSV file into a 1-D array

Hi
I would like to read a csv file into a cluster of 4 elements which would then be read into a 1-D array.
My cluster contains a typedef, a double, a boolean, and another typedef.
Basically it could be seen as:
Bob Runs, 4, T, Bob
Mary sits, 5, F, Mary
Bob Sits, 2, F, Bob
Mary Runs, 9, T, Mary
(keeps growing)
Are there any good examples for what I am trying to put together that I could leverage, or is it better to use a different input file than a csv. I am trying to make my program more flexable and easier to make adjustments even after the executable is created. My line items seem to be growing exponentially and is getting difficult to manage in the LV window.
Thanks
Solved!
Go to Solution.

Unless your CSV file is huge, I'd use "Read from Spreadsheet File" with the delimiter set as "," and the type as string. This will give you a 2D array of strings. You could then separate out each column of the array, convert to the appropriate data type, and use Index & Bundle Cluster Array to build your array of clusters. Something like this (except I'm using a string constant in place of reading from the file).

Reading csv file how to get the Column name

Hi,
I am trying to read a csv file and then save the data to Oracle.
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection("jdbc:odbc:;Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=.;Extensions=csv,txn");
Statement stmt = c.createStatement();
ResultSet rs = stmt.executeQuery("select * from filename.csv");
while(rs.next())
System.out.println(rs.getString("Num"));
My csv file looks like this:
"CHAM-23","COMPANY NAME","Test","12",20031213,15,16
Number,Environ,Envel,Date,Time
"1","2",3,"4",5
"6","7",8,"9",9
Now is there anyway using the above code I start processing the file from the second row that holds the names of the columns and skip the first row. And also can I get the name of the column using ResultSet something like:
if columnName.equals("Number")
Because I may have a csv file that could have more columns:
"CHAM-24","COMPANY NAME","Test","12",20031213,16,76
Number,Environ,Envel,Date,Time,Total,Count
"1","2","3","4","5",3,9
"6","7","8","9",9",,2
So I want to get the column name and then based on that column I do some other processing.
Once I read the value of each row I want to save the data to an Oracle Table. How do I connect to Oracle from my Application. As the database is on the server. Any help is really appreciated. Thanks

The only thing I could think of (and this is a cluj) would be to attempt to parse the first element of each row as a number. If it fails, you do not have a column name row. You are counting on the fact that you will never have a column name that is a number in the first position.
However, I agree that not always placing the headers in the same location is asking for trouble. If you have control over the file, format it how you want. If someone else has control over the file, find out why they are doing it that way. Maybe there is a "magic" number in the first row telling you where to jump.
Also, I would not use ODBC to simply parse a CSV file. If the file is formatted identically to Microsoft's format (headers in first row, all subsequent rows have same number of columns), then it's fine to take a shortcut and not write your own parser. But if the file is not adhering to that format, don't both using the M$ ODBC driver.

Labview not reading csv file properly.

I'm trying to use the read spreadsheet file vi to read the attached csv.
It does a few things incorrectly:
1) the first cell of the resulting array has ÿþ appended to the front of it, seems like labview is grabbing some special character it shouldn't? (Notepad, notepad++ and excel can all open the file without issue and none show ÿþ or anything like it).
2) It's mistreating the EOL characters as two line feeds, resulting in blank rows between each data row. (Looking at the csv in notepad++ confirms that the lines are ended with a CR and a LF (same as EOL).
3) I'm reading it in as a string, because one of the columns is non-numeric, but then I strip that column out and attempt to convert the remaining string array into a numeric array (this fails). It also fails if I pull out an individual element of the array and attempt to convert it to a number (in both cases using fract/exp string to number), below I have an example of trying to read the 2nd column of the 1st row (index: 0,1) which is formatted as a string: "1.37238168716431" and converting that into a number gives 0 as you can see in the snapshot of the front panel.

I guess the file is in unicode, that doesn't help me very much.
I don't use the "Read from Text File Function" - at least not directly, although it is called in Read from Spreadsheet File. Where is it called, however, right-click doesn't show an option for Convert EOL, instead it's a terminal and it's default is F and as the terminal is disconnected, I'm assuming it's not converting EOL. So it's already "unchecked" in a sense.
No idea how to convert the unicode string to ascii. (no functions show up when i search unicode or ascii in the manager). It displays it just fine in the text box, so I'm not sure why it's able to display it without issue but not read it as a number.
Using Labview 8.6, by the way.

Read .csv File and Update DB

I have a .csv file with about 11 columns and multiple rows.
I need to read this file and from each row extract the first
4 columns and update my local database.
If the value if 1st column (unique#) is already in DB do an
Update else do an Insert.
How do I read this .csv file and accomplish this goal?

You read the file with <cffile>
It then becomes nested lists. For the outer list, your
delimiter is chr(10). Each list item is a row from your file. For
your inner list, the delimiter is a comma.
That should get you started. Details list functions and
<cffile> are in the cfml reference manual. If you don't have
one, the internet does.

I made a csv file from DAQ mx.
This file Format is
date(ex: 2007-09-16 11:40:32),data1,data2.... date(ex: 2007-09-16 11:40:32),data1,data2....
I want to draw this file to X,Y Graph or Chart.
But I can't convert this into 2D array. When I covert this into Date by using read from spreadsheet file .vi, Date is converted like this 2007.000
How can I do that?
Could anyone infrom me about this solutions?
regrads.
Kevin.

Also, you should not be basing the location of the path to read from the location of the VI. You should use a file path control because:
(a) You cannot assume the file to read is in the same location as the VI
(b) If this VI is build into an application the path will be different.
Yes, if you built an application, the relative path will be different. Also, if the application is properly installed in the "program files" folder, there will be potential problems in windows Vista if you want to write there.
Still, in a simple development environment it is often convenient to keep data next to the VI in order to test code, so relative paths make sense. Here's the (near) equivalent code to whatever you constructed with the while loop.
It is very important to never (!!!) use path-to-string and string-to-path when manipulating paths, because it will immediately break the code on a different platform (windows, mac, linux). You should use "strip path" and "build path" exclusively! Paths should never exist as strings, just a paths.
Small differences:
In this particular case you need to ensure that the "sub folder" control is not an empty string or you get a <not a path> as output.Your code would just ignore the subfolder.
Your code also requires the sub folder control to end in a "\", while my alternative only needs the name. If you don't end it in a "\", the subfolder will be merged with the filename.
Exception:
The only place where path-to-string and string-to-path should be used os for OS specific tasks, such as forming a commandline for "system exec".

Set-ADUser based on .csv file - empty attributes issue

Hi, after a few months without working with PowerShell my knowledge is slowly fading away but fortunately every time this happened before, I was able to rebuild my knowledge again and now it is the same story. However I want to optimize my simple
code which populates three AD user object attributes: manager, officephone and fax with values stored in .csv file. Everything works well, but my code looks not so good in my opinion. Is there any more elegant solution?
$AddressBook = Import-CSV -Path D:\AddressBookFinal.csv
foreach($Employee in $AddressBook)
     if([string]::IsNullOrEmpty($Employee.ManagerUserName)) {
              Set-ADUser -Identity $Employee.EmployeeUserName -Manager $null
    } else {
              Set-ADUser -Identity $Employee.EmployeeUserName -Manager $Employee.ManagerUserName
    <#similar code here for checking value of OfficePhone and Fax attributes and populating AD attributes depending on if attribute value in .csv file is empty or not#>

SQL server 2014 and VS 2013 - Dataflow task, read CSV file and insert data to SQL table

Hello everyone,
I was assigned a work item wherein, I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current
file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.
On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file. Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?
I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns
in it. These files needs to be migrated to SQL tables using the optimum way.
Does anybody know which is the best way to setup the Dataflow task for this requirement?
Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
Any help would be much appreciated. It's very urgent.

The standard Data Flow Task supports only static metadata defined during design time. I would recommend you check the commercial COZYROC
Data Flow Task Plus. It is an extension of the standard Data Flow Task and it supports dynamic metadata at runtime. You can process all your input CSV files using a single Data Flow Task
Plus. No programming skills are required.
