When I save my data using write char to file, there is a problam when I modify and save the file.

[Alexander J.]

Hi all,
I am trying to save my data using write character to file. But there is a problam. After I modified my file, When I save the file "see my attach" the dialog appear. I think something is not right. PS. I open with excel.
Thanks

The file you generate in LabVIEW is not an excel file but a simple text file...If you open such files (whether they come from LV or any other application) in Excel and then save them, Excel will by default save it as a tab delimited text file. It will pop up that warning to let you know that there might be formatting in the original document or in the new Excel document (e.g. if a formula has been added) that will be left out if it is saved as a tab delimited text file...(hinting that you may want to save it as a true Excel file instead).

If you need to open the files in Excel and want to avoid this message then you need to write a true Excel file from the start...one way to get that done is to use the report generator toolkit.

Mads is right, but you might also try to save the file as a .csv file and instruct Excel to open as a simple .csv file without formatting. There are other formats that will work...You may need to experiment.
