Path syntax & examples
Supported subset: $.projects[0].name · $..name · $.projects[*] · $.projects[0:3] · $['name','version'] · $.projects[?(@.stars >= 10)]
Negative indexes, positive slice steps, existence filters and simple literal comparisons are supported. No scripts, compound filters or full RFC 9535 support. Results are always an array; zero matches is valid.
Guarded parsing: duplicate keys, unsafe integers, underflow and negative zero are rejected to avoid silent data loss. Decimal fractions still use JavaScript precision. Limit: 1 million characters / 100 nesting levels.
Encode / Decode
Go from readable text to encoded data and back. UTF-8 aware by default.
Text Tools
Clean up a snippet, inspect text stats, or see what changed between versions.
Time Converter
Translate Unix epochs and ISO dates into something human-readable.
Conversion results
