Common questions
The checker says my prices "must be a plain number"
Shopify's Price column takes numbers only, like 24.00. Remove $ signs, commas and words such as "Call".
"Barcodes and SKUs weren't damaged by Excel" failed
Excel turns long numbers into scientific notation (8.12345E+11) and the real digits are lost. Export again from the original source and format that column as Text before saving.
"Saved as UTF-8" failed
In Excel use Save As, then choose "CSV UTF-8". Google Sheets exports are already UTF-8.
Can the checker read my file from a link?
Yes, if the link is public and points straight at the CSV. Shared-drive links that open a preview page won't work; download the file and paste its contents instead.
Is my file stored?
No. CSVs are checked in memory and discarded. See the privacy policy.
