Not coming off as obtuse, and i'll try my best to explain the issue but I do understand what you are saying.
The goal is I am doing an import of clients into our system for an integration so the info syncs correctly and we sync using the Client ID, which is case sensitive.
When I imported the data into my system, i want to import the Client ID - 1105416.000 (what i see in the cell). When using my importer tool to match the corresponding fields in our system with the field in the spreadsheet, the value example the importer tool is showing is Client ID - 1105416, which is incorrect. I ran a small sample to test and it imported as 1105416, but it has to be 1105416.000
