When anything is exported to xls, Zoho adds a column with an ID.  WE DO NOT WANT THIS COLUMN.  We use an automated report to a team.  We have our own tracking number.  1. This makes the report messy, it just pushes OUR data off to the right.  2. We have to remind everyone, Zoho forces us to have that field, ignore it, sorry.  No, we do not want to change CRM....   3. It is too much work to have to remove it when sending to someone outside the company.  4. That is private data, Zoho should not expose any of our data to other people without our permission.

This is just a really BAD idea.  STOP adding the column.  This will take very little to program and test.  Obviously you would make it a choice for those that want it.
