What is the UTM bulk generator?
A free, browser-based tool that turns a CSV of campaign rows into tagged tracking URLs in one go. Paste or upload a CSV with a base_url column plus utm_source / utm_medium / utm_campaign columns, and it builds one tagged URL per row. Copy them all or download the result as a CSV. Everything runs in your browser, so your data is never uploaded.
How to use it
- Prepare a CSV with a header row: base_url plus the utm_ columns you need.
- Paste it into the box, or upload the CSV file.
- Review the generated URLs, then copy all or download the CSV.
Common use cases
- Generating hundreds of ad or email URLs from a campaign spreadsheet.
- Producing consistent UTM URLs that import straight back into your sheet.
- Handing tagged links to an agency or another team in bulk.
