Convert/Import TDMS to Excel

So I have some LabVIEW code which logs to TDMS just fine. I installed the TDMS Excel Add on to Excell 2007 and it imports the TDMS just fine and it looks good.
What I would like do do now is instead of just having that TDMS file, I would also like to have the XLS equivalent as well. As if I imported the TDMS in Excel, and then went to save the workbook as XLS or XLSX. So I wanted to programatically import the TDMS file, get the active workbook from Excel, and then programatically save the active workbook as XLS, or XLSX in the same directory as the original TDMS.
I'm having problems with the first step of my plan. I see here there are some details about how to call the TDMS import using ActiveX but when I use it I get an error. Calling ShowAboutDlg or ShowConfigDlg work just fine, but when I call the Import it I get a "An unknown error occured: 0x80004003" which I believe is a invalid pointer.
Attached is the VI I was using to try to import a TDMS file. Saved in 8.20, running TDM Importer 3.1.0.25, with Excel 2007, on XP SP3. Thanks.
EDIT: The VI is pointing to a TDMS file which comes with LabVIEW 2009, this path may need to be changed.

Import TDMS 82.vi ‏9 KB

Yeah sorry forgot that I used that OpenG VI, attached is another version which doesn't use it for those of you not on the OpenG bandwagon.
I've been using this VI for a little while now and it's worked great on several machines. But recently I've started to see problems where I get an error 97, LabVIEW: Null Refnum was passed in as input.
This happens for me coming out of the property node ITDMAddin. I probed the reference going in and its value is 0, with the variant data also of value 0. Any ideas on how this could happen or what can be done.
I changed the COMAddIn propety node from Object to Description and the string is "National Instruments TDM Importer for MS Excel" So that makes me believe that I am getting the reference to the AddIn but for some reason the Object property returns a value of 0.
EDIT: Okay I think I figured it out, if Open New Instance is TRUE for the Open Automation it works fine. Not sure why but it fixes it, a new version with the fix is up.

Double datatype in tdm which is converted from tdms

Hi all,
In short, to be able to delete channels and groups from a tdms file, I convert the file to a tdm, delete channel or group by making use of storage VIs, and convert it back to tdms. The problem is, when tdms is converted to tdm, double data types (64-bit) became single (32-bit) types. Original tdms file has doubles in it, but tdm and resulting tdms files have singles.
Attached VI does things I mentioned above. After running it, I open tdms-1.tdms in Excel with tdm importer (v3.3.0.0), and datatype is DT_DOUBLE. But in tdm.tdm and tdms-2.tdms files, datatypes are DT_FLOAT. So the question is, is there a way to prevent doubles from being converted to singles?
Note: I have to convert tdms file to tdm, because storage VIs which deletes channels and groups do not work with tdms format.
p.s. I'm on LV2011.
Solved!

Application builder changes tdms to excel vi

I had a tdms to excel vi that was working great. So I tried to make the whole program into an executable. I have done this before without incident. So I went to close the source program and it asked me if I want to save (most specifically the tdms to excel sub-vi). It was more of a strongarm tactic since I couldn't close it without saving. Now, both the executable and the source program open the first file, convert it to excel format (as intended) and close it again, but them fails to do it for any other files in the array that I generated. A little trouble shooting..... I opened other programs and ran them successfully. upon converting them into an executable, it asks me to save changes to the tdms to excel vi, which, I never touched. this resulted in duplicating the problem stated above.

thomas,
I'm minorly confused so let me ask a clarifying question: Does the VI still function properly but you are just being prompted that "something has changed" by your source code control?
If it's just the "needing to save changes when none were made" issue and not that your code is no longer working then this article (http://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/saving_vis_compiled_code/) might help explain why LabVIEW asks for changes. Even though changes aren't physically made by you, there are changes being made.

How can I convert word labels to excel

I have just purchased this Adobe ID program and paid for a years subscription.
Can someone tell me how I can take Microsoft word 2010 labels already saved on my flash drive and convert them to an excel spreadsheet with headers such as:
Name Address City State Zip Code
I have been attempting to do this for the last 8 hours today, and still can't get it right.
Help???

HI melodymorganclockwork,
What Adobe program did you purchase? If you have a Word file that you want to convert to Excel, I don't think it's necessary to make Adobe part of the equation.
But I found this document that might help: http://smallbusiness.chron.com/convert-mailing-labels-columns-excel-40828.html

How does DIADEM import TDMS files? How gets every channel his number and groupindex? How can I determine which channel has which groupindex and number?

I store different channels in a TDMS file.
I like to have a time channel at the first position with group index 1 and number 1.
When I read the TDMS file with DIADEM the time channel (Float64) is on a differernt position, and the channels are not sorted alphabetically.
Here are my questions:
How does DIADEM import TDMS files?
How gets every channel his number and groupindex?
How can I determine which channel has which groupindex and number?
Best regards
Joerg

Hi Jörg,
i suppose that you´re programme whose create the *.tdms file is writing on false position. Try to create datas with timechannel on first indes in diadem, then save it and then open it again. you see that all is correct. So please tell me what programm in what version do you use and please attache it here.
Did you use the library for creating *.tdms files like in the link ?
http://zone.ni.com/devzone/cda/tut/p/id/6471
Here you find the gtdms_8.x.zip - when you extract it and opened the *.llb you find vi´s for all functions e.g. writing 2d array of strings to *.tdms file
when you open the subvi´s then you see how created and writing datas/structure to *.tdms files. Because *.tdms is binary you can´t see structure with open it in editor.
When you don´t have Labview you can use the 30 days test of current version 8.5 under following link
german version download link

Import data from excel/csv file in web dynpro

Hi All,
I need to populate a WD table by first importing a excel/CSV file thru web dynpro screen and then reading thru the file.Am using FileUpload element from NW04s.
How can I read/import data from excel / csv file in web dynpro table context?
Any help is appreciated.
Thanks a lot
Aakash

Hi,
Here are the basic steps needed to read data from excel spreadsheet using the Java Excel API(jExcel API).
jExcel API can read a spreadsheet from a file stored on the local file system or from some input stream, ideally the following should be the steps while reading:
Create a workbook from a file on the local file system, as illustrated in the following code fragment:
          import java.io.File;
          import java.util.Date;
          import jxl.*;
         Workbook workbook = Workbook.getWorkbook(new File("test.xls"));
On getting access to the worksheet, once can use the following code piece to access individual sheets. These are zero indexed - the first sheet being 0, the second sheet being 1, and so on. (You can also use the API to retrieve a sheet by name).
          Sheet sheet = workbook.getSheet(0);
After getting the sheet, you can retrieve the cell's contents as a string by using the convenience method getContents(). In the example code below, A1 is a text cell, B2 is numerical value and C2 is a date. The contents of these cells may be accessed as follows
Cell a1 = sheet.getCell(0,0);
Cell b2 = sheet.getCell(1,1);
Cell c2 = sheet.getCell(2,1);
String a1 = a1.getContents();
String b2 = b2.getContents();
String c2 = c2.getContents();
// perform operations on strings
However in case we need to access the cell's contents as the exact data type ie. as a numerical value or as a date, then the retrieved Cell must be cast to the correct type and the appropriate methods called. The code piece given below illustrates how JExcelApi may be used to retrieve a genuine java double and java.util.Date object from an Excel spreadsheet. For completeness the label is also cast to it's correct type. The code snippet also illustrates how to verify that cell is of the expected type - this can be useful when performing validations on the spreadsheet for presence of correct datatypes in the spreadsheet.
String a1 = null;
Double b2 = 0;
Date c2 = null;
                    Cell a1 = sheet.getCell(0,0);
                    Cell b2 = sheet.getCell(1,1);
                    Cell c2 = sheet.getCell(2,1);
                    if (a1.getType() == CellType.LABEL)
                       LabelCell lc = (LabelCell) a1;
                       stringa1 = lc.getString();
                     if (b2.getType() == CellType.NUMBER)
                       NumberCell nc = (NumberCell) b2;
                       numberb2 = nc.getValue();
                      if (c2.getType() == CellType.DATE)
                        DateCell dc = (DateCell) c2;
                        datec2 = dc.getDate();
                       // operate on dates and doubles
It is recommended to, use the close() method (as in the code piece below)   when you are done with processing all the cells.This frees up any allocated memory used when reading spreadsheets and is particularly important when reading large spreadsheets.
          // Finished - close the workbook and free up memory
          workbook.close();
The API class files are availble in the 'jxl.jar', which is available for download.

Raghu

Error while importing data from excel to forms

Hi,
I am working on Oracle forms 10g, and I'm supposed to import data from excel sheet to forms.
While the user enters the data,sometimes after entering a particular word he/she hits the alt+enter button.
As a result the data appears in two lines in a single row
So,when I try to import the data it's not importing the data in a right manner.
S0,I want to replace this linefeed and carry with five spaces.
Eg:The user instead of entering Geekpedia enters Geek
pedia
in the excel sheet.
Now when I import this in the forms I want it to be imported as Geek Pedia.(5 spaces between Geek and pedia).

Maybe you can consider save excel as .csv files and then you can load them as flatfiles to external table in OWB.

What happens when you convert to excel?

Is there a way to import data from excel -when one of the columns in excel is hyperlink column?

Is there a way to import data from excel - so if a column is hyperlink - the whole data will move to the list (text + link of the hyperlink column)?
keren tsur

Hi,
According to your description, you want to export excel which contains a hyperlink column to SharePoint list.
Refer to the following steps:
Open the Excel, insert/create the table.
Now click on any cell of table and go to the ‘Design Tools’.
Click on the Export and then ‘Export table to SharePoint List’.
You will see a popup where you need to provide the URL of SharePoint site, list name and description.
Then click on next, On the next screen you will see columns with data types which are going to create in SharePoint list.
Now click finish and wait until the operation gets finished. You will see that list gets created in SharePoint site with the records.
Here are two links, you can use as a reference:
