Pulldata is removing leading zero converting trailing numbers to zeros

Dear all,
We are doing a project that should pull information from a CSV file under media using ODK central, using the pulldata function.
On the CSV file, if a field has a value of 012006601060061884 the pulldata omit the leading zero and replace the trailing numbers (84) with 00.
Please can someone help me?

Hi @gerald_thomas Have you tried to set the field value into quotes (") in order to mark it as string? Elsewise, I suspect the value is detected as a number and therefore parsed in some way or the other, leading to your issue.

Noted with thanks
