Hi Tony,
Thank you for the update.
Currently, we do not have support to preserve the leading zero with the numbers while importing the data table in XlsIO. So we request you to open a new direct-trac incident with a simple issue reproducing sample for further follow up on this forum.

Please set the number format to display the values with leading zero as given in our previous post.
Please let me know if you require any further clarifications.
Thanks,
Sridhar.S
