Code Transformer & LLM Sanitizer

Convert code and config between formats — JSON to YAML, YAML to JSON and more — then flip on AI Safeguard to automatically redact API keys, tokens, passwords and PII before you paste anything into ChatGPT, Claude or another LLM. Everything runs 100% locally in your browser: nothing is uploaded, so it's safe for proprietary and client code.

How to sanitize code before pasting into an LLM

  1. Paste your code, JSON or YAML into the source panel.
  2. Pick a transform mode, or let it auto-detect the format.
  3. Enable AI Safeguard to redact secrets and personal data.
  4. Copy the clean, converted output — ready to share or paste into an AI tool.

Frequently asked questions

How do I convert JSON to YAML?

Paste your JSON into the source panel and choose the JSON → YAML mode (or auto-detect). The converted YAML appears instantly and can be copied with one click.

How do I remove secrets before pasting code into ChatGPT?

Turn on AI Safeguard. It scans for API keys, tokens, passwords, emails and other PII and redacts them, so nothing sensitive leaves with the code you paste into an AI assistant.

Is my code uploaded anywhere?

No. All transformation and redaction happens locally in your browser — there is no backend and nothing is transmitted, so it's safe for proprietary code.

Is this tool free?

Yes, it's completely free with no sign-up and no limits.

Need to pull structured data (emails, IPs, hashes, API keys) back out of text instead? Try DataExtract. Testing email HTML too? Try the HTML email tester. You can also find the Code Transformer on IgnLab Launch or browse more free tools in the directory.
