Hi Kerri Keohane,
What program are you using to 'process' the csv file?
Are you using Excel? Did you try to mark that column as 'text' in Excel and then exporting as csv?
I think you have that column as 'number' and that's why Excel is removing the trailing zeros. If you tell Excel that it is to be treated as text, it would not do it.
Please feel free to reach out at Rajesh@BrightHooks.com if you have any questions. Hope this helps.
