FAQ

Which UTM parameters are required?

By default it requires utm_source, utm_medium, and utm_campaign. You can turn strict mode off if you only want extraction.

Does UTM casing matter (UTM_Source vs utm_source)?

Many analytics setups expect consistent keys; mixed casing can cause messy reporting. This tool flags casing and can normalize keys to lowercase.

What does “Deduplicate UTM keys (keep last)” do?

If a URL has utm_source twice, the cleaned URL keeps only the last value for each UTM key. This avoids ambiguous tracking.

Will this tool change non-UTM query parameters?

No values are modified; it can optionally sort parameters for readability. Non-UTM parameters are preserved.

Can I check multiple URLs at once?

Yes—paste one URL per line. The output includes a per-URL report plus a summary count.

Is this tool offline and private?

Yes. It runs locally in your browser and does not send your URLs anywhere.

Can I export the results?

Switch the output format to CSV and copy it into Sheets/Excel. The CSV includes extracted UTMs, issues, and the cleaned URL.
