How do I generate UTM URLs in bulk?

Paste or upload a CSV with a base_url column plus utm_source / utm_medium / utm_campaign (and optional term/content) columns. The tool builds one tagged URL per row, which you can copy all at once or download as a CSV.

How should I name the CSV columns?

Use a header row: name the URL column base_url (or url) and the UTM columns utm_source, utm_medium, utm_campaign, utm_term, utm_content. Short names without the utm_ prefix (e.g. source) are also recognized.

Can I use data from Excel or Google Sheets?

Yes. Export your sheet to CSV and paste it, or upload the file. The generated URLs download as a CSV too, so they import straight back into your spreadsheet.

Is there a way to build URLs one at a time?

For just a handful of URLs, the UTM URL Builder is easier — a form-based builder that also lets you add multiple rows.

Is my CSV uploaded to a server?

No. Parsing and URL generation happen entirely in your browser; your data is never uploaded or stored on a server.

Yes, it is completely free. No sign-up and no installation required.
