How to use this tool
How to use this utility
Fill the labeled fields
Paste YAML/JSON/TOML, .env lines, PEM blocks, HTML snippets, or numbers—whatever the tool expects. Trim huge samples if you only need a quick check.
Validate locally, then Run
The page checks obvious issues first. Press Run only when the payload looks right; the server rejects malformed JSON or missing required fields.
Read the JSON result
Outputs are structured objects (numbers, arrays, maps). Copy the fields you need into editors, tickets, or spreadsheets—nothing is kept after the response.
Treat outputs as informational
Financial, legal, crypto, or accessibility figures are estimates—verify with authoritative tools before commitments. Do not send production secrets you cannot rotate.
