How to name columns when writing data to a file

[Doagie]

Hi all, I am inputting 2 signals into the "Write LabView Measurement File" subVI/control thing, and although the data saves correctly, there is no column heading for each set of y-values. How do I get it to name these? Thanks.

I was about to post the same question, except for Excel (or any spreadsheet) files. No matter how I wire things, I'm getting broken wires and "bad data type" errors.

For normal ascii data files you can write the column headers before you actually take the data by simply writing the headers as text to the file using the Write Characters to File function.

If you use the separator in that header file that you are using for the spreadsheet data and follow the header line with a CR/LF constant it will show up nicely at the top of your data file and be formatted like you want it to be in Excel as long as you append the file and do not write to a new file.
