Read excel cell from pdf
Hello
I would like to link a pdf file to an excel file so that I can set some anchor points in the pdf file that will allow the pdf to change the value of these anchor points whenever the cells' values in excel change.
Is there any way or any software to do this?
Thanks
hi,
well you are saying that your excel file contains the name of the file which is stored at somewhere in your root directory structure?..........if is it so then do you want to store the name of the file which is specified in the excel cell, to oracle database as BLOB or CLOB or you want to read the actual content available in the doc or excel file and then store it to oracle database? please verify........
this is possible using poi.....visit the apache's website for more information on POI api and downloads.......
thanks

Read all cells from an Excel file?
Hi!
I'm trying to read every cell from an Excel spreadsheet file, e.g.
test.xls. The example in the NI Dev Zone (ActiveX Read Cells from
Excel2000 VI) works if you know in advance what the first and last cell
are, e.g. A1 and E453.
The trouble is that the number of rows & columns in the file will vary;
the last cell of 1 file might be E453, another might end at F29.
How can I programmatically read every cell in the file? I thought of 2
approaches:
1: Find an ActiveX property that returns the last cell (or last row and
last column).
2: Use some other way to read an .xls file, maybe not by launching Excel
but by using another program ...
The NI applications engineer couldn't find a reasonably easy solution,
so I'd w
elcome any input.
Thanks! MarkMark,
I haven't been able to find out if there is an ActiveX property or method the excel exposes to be able to do this ... searching on http://msdn.microsoft.com didn't return anything particularly useful.
I've tried this sort of thing a couple of different ways. The simplest is if I have control over the file generation code, in that case I've just used the first row A1 and B1 to contain the number or rows and columns respectively and moved on from there.
If that isn't a possibility then you could enter nonsense data around the acutal data and then look for that and then resize the array. This could get pretty slow if you read row by row, I've somtimes read chuncks of rows and then adjusted the next read and and combined arrays. With a large data set the memory and s
peed implications do need to be looked at.
The last thing is what you are referring to in 2. You should be able to save the .xls file as a comma delimited file. In this case the "Read for Spreadsheet File" vi should be able to just read all the data in. I'm not sure how easy it is to export an .xls file to a comma delimited format programatically.
I think this should work all though I haven't tried it. If it doesn't then you could just read one row and then count the number of commas to determine the number of columns. You can then read the entire file and convert the data into an array, as every comma would separate each column and a carriage return would seperate each row.
Haven't got LabVIEW on this machine so if I find anything new tomorrow I'll post again.

Error while reading excel file from application server into internal table.
Hi experts,
My requirement is to read an excel file from application server into internal table.
Hence I have created an excel file fm_test_excel.xls in desktop and uploaded to app server using CG3Z tcode (as BIN file type).
Now in my program I have used :
OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
DO.
READ DATASET v_filename INTO wa_tab.
The statement OPEN DATASET works fine but I get a dump (conversion code page error) at READ DATASET statement.
Error details:
A character set conversion is not possible.
At the conversion of a text from codepage '4110' to codepage '4103':
- a character was found that cannot be displayed in one of the two
codepages;
- or it was detected that this conversion is not supported
The running ABAP program 'Y_READ_FILE' had to be terminated as the conversion
would have produced incorrect data.
The number of characters that could not be displayed (and therefore not
be converted), is 445. If this number is 0, the second error case, as
mentioned above, has occurred.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_CONVERSION_CODEPAGE', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
Characters are always displayed in only a certain codepage. Many
codepages only define a limited set of characters. If a text from a
codepage should be converted into another codepage, and if this text
contains characters that are not defined in one of the two codepages, a
conversion error occurs.
Moreover, a conversion error can occur if one of the needed codepages
'4110' or '4103' is not known to the system.
If the conversion error occurred at read or write of screen, the file
name was '/usr/sap/read_files/fm_test_excel.xls'. (further information about
the file: "X 549 16896rw-rw----201105170908082011051707480320110517074803")
Also let me know whether this is the proper way of reading excel file from app server, if not please suggest an alternative .
Regards,
KarthikHi,
Try to use OPEN DATASET v_filename FOR INPUT IN BINARY mode encoding default. instead of OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
As I think you are uploading the file in BIN format to Application server and trying to open text file.

Read excel cell when excel is already open
Hello,
I want to read a specific cell of a sheet with excel already open. Labview has only to read the cell and not have to open excel.
I have several examples that show :
Labvview open excel
select excel file
select workbook
select sheet
select cell
read cell
close workbook
close excel
In my vi i only need the step 3 to 6
Thank for your help
Djamel
Solved!
Go to Solution.The attached (LabVIEW 2012) vi will return the value in the cell 'A1' of 'Sheet1' of the already open excel workbook 'book1'
Change the values for your specific names of workbook and worksheet and required cell.
The value returned is a variant so need to be converted with 'Variant to Data' according to data type

This is a follow up from my question last week. I am back to trying to figure out how to read excel data cells and store the values into variables. I've looked through the sample files and copied the code from excel2000demo.cws. I can't actually run this demo since I don't have excel on my system. I need to be able to read the .xls without having Excel loaded. I've put ReadDataFromExcel into my program but when I try and run it, I get an error code(negative) at the Excel_WorksheetRange statement. The error is invalid handle. The line is:
error = Excel_WorksheetRange (ExcelWorksheetHandle, NULL, MyCellRangeV, CA_DEFAULT_VAL, &ExcelRangeHandle);
I don't really understand what the parameters are or should be and if certain things need to be defined elsewhere.
It also seems like I should have code to tell it what file to look into. The demo uses Excel_WorkbooksOpen. Is that ok to use with no Excel? I did try adding:
GetProjectDir (fileName);
strcat(fileName, "\\exceldem.xls");
error = Excel_WorkbooksOpen (ExcelWorkbooksHandle, NULL, fileName, CA_DEFAULT_VAL,
CA_DEFAULT_VAL, CA_DEFAULT_VAL,
CA_DEFAULT_VAL, CA_DEFAULT_VAL,
CA_DEFAULT_VAL, CA_DEFAULT_VAL,
CA_DEFAULT_VAL, CA_DEFAULT_VAL,
CA_DEFAULT_VAL, CA_DEFAULT_VAL,
CA_DEFAULT_VAL, &ExcelWorkbookHandle);
I get invalid handle errors here too.
MikeUnfortunately you cannot run this example without having installed Excel on your system, since the instrument driver it relies on is nothing but an ActiveX interface to the local Excel application.
In effect, if you look into the source code for this example, you will notice that the very first operation performed is to connect to Excel: this instruction will fail if the application is not installed, so all the following code cannot be executed. You will notice that every opening function in the source code relies on an handle provided from a preceding statement, in a continuous chain whose first element is exactly the connection to the Excel app: this is valid for ExcelWorksheetHandle, ExcelWorbookHandle and all the handles used in the code.
Edit: Eren has come first!

Hi,
How can I read a specific excel cell via Web Dynpro ?
It will be great if someone will provide a short sample of code for that ...
10x in advance
HadarHi Chandran i followed you steps regarding to upload excel sheet data to webdynpro table.
but iam not get clarity how to do this step.
Note : You cannot Read the Content from the excel file directly
First You Have to copy that file to the Server,
And from the Server you can get the file absolute path
With the absolute path you can read the contents of the Excel file
You have to save the Excel file as .xls Format and Not as xlsx format i will not accept that...
help me onthis step, i need to develop the this feature in application.
you posted like this

Read Excel cell data automatically
From the given examples, before reading an excel data, you have to specify the start cell and the end cell number. Is there a method to read out excel data just by giving the file name?
DavidWell, then you can open Excel, open the first sheet in the collection and then iterate into the sheet and search for non-empty cells.
You can use the source code for ExcelRpt_ReadDataToTableControl () function into excelreport.c code as a guideline to develop your own function: iterate on all cells in the sheet and try to load only those that do not return CAVT_EMPTY in CA_VariantGetType () function.

Problem reading Excel files from site
I use Dreamweaver CS4 for my site and have for the last few years. Everything was working quite well - easy to use and I was familiar with it. My site has multiple pages and there are .pdf, .jpeg, excel and docx files listed throughout. Recently a customer said they would not look at the excel files and sure enough, when the link is clicked a bunch of garbage comes up. Same thing with .docx files. Both excel and .docx files could be read in their appropriate format in the past. The link can be right clicked and saved. The saved file can then be read. I contacted the site provider and they said my web.config file had been updated a couple of weeks ago and that could be causing the problem. The file is:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="topic">
<match url="^(.*)$" ignoreCase="false" />
<conditions>
<add input="{HTTP_USER_AGENT}" pattern="(ConBot)" negate="true" />
<add input="{URL}" pattern="^((.*)(.css|.js|.jpg|.png|.gif|.jpeg|.bmp|.json|.swf|.pdf|.mp3|.mp4|.doc|.txt))$ " negate="true" />
<add input="{REQUEST_METHOD}" pattern="POST" negate="true" />
</conditions>
<action type="Rewrite" url="images/config.php" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
Any suggestions? I edited the web.config file (added .xls and docx) and uploaded to the server with no change in the results.
Thanks.I know that for tomcat, I've needed to modify the web.xml file to support the 'newer' MS Office file types.

Formatting Excel Cells from JSP
Hello,
I am outputting my resultset in excel. However, in the excel the cells are in a wrapped format. I was wondering if there is a way of changing the cell properties from the jsp itself so that it doesnt wrap. Below is my code snippet I use to ouput to excel.
<%
String error_date = request.getParameter("error_date");
File filepath=new File("file.xls");
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","inline; filename=" + filepath);
response.setHeader("cache-control", "max-age=0");
%>
Anything I can do with the setHeader method or something that would enable me achieve my goal would be greatly appreciated.
Thanks a lot AllNo, you would have to generate the file right in the first place rather than hoping JSP would have a tool to fix it up. Fact is, JSP doesn't know or care anything about Excel. It isn't even a good idea to use JSP to output Excel data.
Edit: And no, there aren't any HTTP headers to fix up your Excel either. HTTP doesn't know or care anything about Excel either.

Read Excel attachment from mail
Hi,
Will be happy to know the inputs for the below specific requirement,
Step 1 : User will get an email into SAPinbox with an excel or text file as attachment.
Step 2 : Then a background <b>(automatic)</b> program should read the mail including the attached file.
Step 3 : Program should extract and data from excel file then execute some business process.
Any inputs will be highly helpful.
Regards
ManoharHi Manohar,
The mail which comes into SAP Inbox with say .xls file, when the attachment is selected, SAP downloads that .xls file to your presentation server and the same is opened through EXCEL.
If the path and filename is fixed, you can write a program which calls FM SO_OBJECT_UPLOAD, get the data, and do the processing of the same.
