Do I need a developer?
No. If you can edit a spreadsheet, you can use it. The plugin handles the WordPress side.
Is it safe on a live site?
The check step writes nothing, so you can look at the numbers first. If the import goes wrong, you can undo it for 30 days. For very large jobs, test on a copy of your site first.
Will running the same file twice create duplicates?
No, if you tell it what makes a row unique — a product code or a title. Then it updates instead of creating copies. If you have not set one, it warns you before the import starts.
What happens to rows with a mistake in them?
A bad row does not stop the import. The plugin lists each bad row and says what is wrong and how to fix it. You can fix those rows and run just them again.
Can I close my laptop while it runs?
Yes. The import runs on your web server, not in your browser. You can close the laptop and check the history page later.
What does it cost?
The plugin is free, and everything on this page is in the free plugin. Importundo Pro is a paid add-on for heavy users: €59 a year for one site, €199 a year for unlimited sites. It adds import from a web address, saved templates, export, and a longer undo window. What Pro adds →
Is the undo a backup?
No. It undoes one import and touches nothing else. Keep normal backups too.
