How to keep the barcodes intact when importing product list?
When you enter a number over 12 digits in an Excel spreadsheet, it auto-corrects the number to scientific notation for brevity.
If you export the product list, excel auto corrects them to a scientific notation. On importing the barcodes can get updated into the system, thus changing them unintentionally.
Here are 3 options on how to avoid this
Option 1: Format barcode column
The following video shows how you can format the barcode column on exporting the list.

Option 2: Remove barcode column before importing
You may remove the barcodes column from product list before importing it.
If you remove any column before importing (except the id column), its value remains intact in Sumtracker.
Option 3: Use Google spreadsheets
You should upload the file exported from Sumtracker as it is to Google drive for this to work.
