How to use this tool

1. Enter code and choose its language.

Processing rules and reading the result

Language parsers load on demand in a separate worker. Formatting organizes whitespace/style; it does not execute, type-check, lint or audit code for vulnerabilities.

Limits and checks before use

Up to 200,000 characters and 8 seconds; complex work is terminated. No project config files/plugins are read beyond selected options. Keep the original and compare against your real toolchain.
