When using the Product CSV Upload tool, How many lines on the CSV file can Shopify process from the same file? Is there a limit on how many lines the feed file can have? (5000 lines, 10000 lines, 100000 lines, etc.)
Hi @greenadventures ,
There’s no limit on how many lines the file can have as long as it doesn’t exceed 15 MB.
However, please note that when a shop has over 50,000 variants, the number of variants that shop can create a day is 1,000. If you exceed this limit, then an error is displayed and you need to wait 24 hours before you can add variants by using an app or CSV file import. Plus stores are exempt from this limit.
These are stated in the following guides:
I hope it helps.
