Frequently asked questions
Does the destination template need example rows?
No. RepeatKit reads the destination headers; template example data is not added to the output.
Does it automatically guess all mappings?
It suggests some matching names, but you should verify each mapping before exporting.
Does it upload my templates to a server?
No. Source and template processing runs locally in the browser.
