Overwritting x_value column in .lvm file

[scottcolston]

Hi

The x_value column in my spread sheet is not what I need it to be. Is there a VI i can use that replaces the X_value column with 0, 1, 2, 3.... down to the end of the file?

Thanks

Hi scottcols...,

you have to read the entire file, change the column and write the new file. If you know the byte position, then you can overwrite it without reading the entire file, but i think it's not very fast.

Do you have to create a new file in the future, or do you only have to change existing files? Maybe it's easier to write the file directly as you need it.

Thanks for the reply. Im not too sure how to do this.

Ive attached an example of the files I have. I want the X_Values= column to read 1, 2, 3, ...n down the rows. 

Can anyone made a simple VI that can do this?

Thanks

Scott
