Regex Tester

Regex Tester is built for data engineers who need to inspect, debug, and explain data artifacts when something breaks in staging or a support ticket lands on a daily basis. Unlike browser-based utilities that ask you to upload production samples, DataEngUtils runs locally on macOS so sensitive values never leave your machine. Use the free in-browser preview for quick checks, then download the native app for offline speed, sidebar search, and the full Regex Tester workflow alongside 20+ pipeline tools in one sidebar. Whether you are debugging a failed dbt run, preparing a handoff for analytics, or validating a file before it lands in Snowflake or BigQuery, Regex Tester keeps the work on your Mac.

How it works

  1. 1. Open the tool

    Launch Regex Tester from the DataEngUtils sidebar or open the browser demo on this page.

  2. 2. Paste or drop your input

    Add the text, config, or file Regex Tester expects. Nothing is uploaded to a remote server.

  3. 3. Review and export

    Inspect the result, copy it to your clipboard, or save output directly from the native macOS app.

Why not use an online tool?

Online inspectors tools require uploading your pipeline inputs to a third-party server. For production work, that is a security and compliance risk. DataEngUtils runs locally — same convenience, none of the exposure.

Frequently asked questions

Is Regex Tester free to try?
Yes. You can try a browser demo on this page for quick tasks. The full native macOS app includes 20+ tools with a one-time license.
Does Regex Tester upload my data?
No. DataEngUtils processes pipeline data and secrets locally. Unlike online inspectors tools, your production data never transits through a third-party server.
Can I use Regex Tester offline?
Yes. After you download DataEngUtils and activate your license, Regex Tester works fully offline on macOS 13+ with no account required for day-to-day tool use.
How is Regex Tester different from a website converter?
Web tools optimize for anonymous uploads and ads. DataEngUtils optimizes for privacy, repeatability, and multi-GB files — the same convenience without compliance risk.
