Bulk UTM builder
Turn a CSV of destinations and campaign values into a clean batch of tagged URLs.
Comma or tab separated. A header row is optional.
| Tagged URL | Status |
|---|
Build many consistently tagged campaign URLs from pasted rows. Supply one destination per line with source, medium, campaign and optional content, then copy or download the finished CSV.
One row becomes one tagged URL
Paste comma- or tab-separated columns in the order URL, source, medium, campaign and content.
Existing parameters are preserved
UTM values are added with the URL API, leaving unrelated query parameters and fragments intact.
Frequently asked questions
Should campaign names use spaces?
Consistent lowercase names with underscores or hyphens are easier to group. The URL itself safely percent-encodes spaces.
Does this contact the destination?
No. URLs are parsed and rebuilt entirely in your browser; no request is made.
