File Format error. Please use the current Data Hub Import Template.
Here are two other common reasons for this error:
Reason #1: Column names were moved or changed.
You may have changed a column name, rearranged the columns, or deleted a column. To correct this error, click the Download All Available GTINs template again, and enter this content or paste the content from the company’s source file, without altering any columns in the template. Then save and resubmit this update file.
Reason #2: Hidden Characters are in the data
If you pasted this product data from another spreadsheet of software, GS1 US Data Hub may be detecting that this data contained hidden line breaks or hidden characters, such as hidden carriage returns.
To remove this hidden data, click the Download All Available GTINs template again, then cut and paste the data from your company’s product source file into this new template. But this time, when you paste the data, select the “Paste as Values” option. Then click CTRL + H to display the “Find and Replace” window. In the “Find” box, type the CTRL and J keys. You will see a flashing dot in the box. Keep the “Replace” box empty. Then click “Replace All.” Save this update file and submit again.
