From eBay: "Starting June 15, sellers will be progressively migrated from File Exchange to Seller Hub Reports. File Exchange will be fully deprecated by Fall 2021."
For more information on File Exchange and the new changes in full please see:
"If you previously used File Exchange you will find most of its core functionality is now in Reports, including the ability to create active listings reports, sold reports and revise price and quantity reports.
The downloads and uploads of your reports and templates in Reports should be familiar to you from the old File Exchange tool. All commonly used reports and templates are backwards compatible."
When you have ran our Parts Compatibility Finder tool and you have downloaded our File Exchange file it may need a couple of small tweaks to suit the new format in order to upload into the Seller Hub Reports.
You can access Seller Hub Reports from the top navigation bar in Seller Hub:
From there you go to Download Template:
After you have downloaded the template, you then merge the file you downloaded from our Parts Compatibility Finder tool to suit the new eBay seller Hub Reports template.
As we mentioned above File Exchange is being fully discontinued in Fall 2021 with eBay adding more functionality in Seller Hub Reports between now and then.
