How to Use This Tool

Generate tagged URLs by row while preserving invalid and duplicate campaign records. Build UTM-tagged URLs from CSV rows, normalize campaign labels, flag malformed URLs and duplicate outputs, and export the complete batch locally.

The work this page finishes

Campaign teams repeatedly tag lists of destination URLs, and one capitalization variant or malformed row fragments analytics while a duplicate silently wastes review time. A visible row-by-row result preserves provenance, making a single correction possible without rerunning unrelated records or uploading the batch.

Rows or choicesValidate every itemReview and export
The fixture produces two unique tagged URLs and one invalid input row.

Deterministic workflow

Require four columns, normalize UTM labels to lowercase underscore tokens, preserve existing queries and fragments, then identify duplicate final URLs. Input guards stop after 5,000 records or 2 MB, and the report separates fatal input problems from recoverable row warnings.

Why a dedicated interface helps

Import the output only after checking that the chosen naming taxonomy matches the analytics property; deterministic normalization is useful only when the team adopts it consistently. Deterministic ordering, one-click copying and a downloadable artifact make repeated operational review easier than manually reconstructing a response from prose.

Assumptions

  • Every row contains URL, source, medium and campaign in that order.
  • HTTP and HTTPS destinations are allowed.
  • Lowercase underscores are the team's approved normalization.

Do not discard the source after export: compare the destination result with it, and remember that local execution cannot secure the surrounding device or browser add-ons.

Limitations and review boundary

It does not shorten URLs, contact landing pages, verify analytics collection, replace existing UTM parameters or decide a universal taxonomy. User values are never run as script, rendered as markup or fetched as network destinations; the page writes them only into text nodes.

Verification and provenance

On 2026-08-26, the rule and examples were cross-checked with WHATWG URL Standard, including a known result, a rejected input and a conflict or duplicate case. The fixture produces two unique tagged URLs and one invalid input row.
