Bulk UTM decoder
Turn a pile of links into a campaign table
Paste URLs from a spreadsheet, Ads Editor export, or ESP. One per line. We pull the tags so you can see which rows will split in GA4 before you argue about last quarter.
When a list is the only honest audit
A single decode tells you what one URL did. A launch review needs every final URL from Google Ads, Meta, and the newsletter sitting in one table. That is how you find Facebook next to facebook, three spellings of a spring sale, and the email that shipped with no campaign name.
Cap is 150 unique URLs per run so a pasted workbook does not lock the tab. After the table, open rows that look wrong in the validator or cleaner. The written process is in how to audit campaign URLs.
Need to create the next batch instead of reading the last one? Use the bulk UTM generator.
FAQ
UTM builder questions
What is a bulk UTM decoder?
It reads a list of campaign URLs and pulls source, medium, campaign, content, and the likely GA4 channel group into a table you can download as CSV.
How is this different from the single decoder?
The single decoder is for one messy paste from Slack. This tool is for an audit: last month’s ads, a partner sheet, or every button in an email program.
