Encode UTF-8 text as hexadecimal bytes and decode hex back to text. Inspect packet dumps, color-ish strings, and binary-safe debug output without a remote hex encoder.

About this tool
Encode UTF-8 text as space-separated hex bytes, or decode hex (spaces and 0-9a-f) back to text. Odd-length hex fails fast so you do not get a truncated character.
How to use: paste text, pick Text → Hex, copy. Reverse for a dump from a debugger. Decoding uses TextDecoder so multi-byte UTF-8 round-trips.
Example: Hi becomes 48 69. A hex dump of a short token never hits a remote encoder. This is not a hex editor for files. Paste the bytes as text.
Encoding is local. Related: binary converter for bit strings, Base64 for a denser transport alphabet. After load, conversion works offline.

JSON ↔ YAML
Convert JSON to YAML and YAML back to JSON in the browser. Paste a config, Kubernetes snippet, or API fixture and copy the other format. Parsing uses js-yaml locally. Documents are never posted to a converter.
JSON ↔ TOML
Convert JSON objects to TOML and TOML documents back to JSON in the browser. Handy for Cargo.toml, pyproject, and app config fragments. Parsing stays on-device.
JSON ↔ XML
Convert JSON objects to XML and XML documents back to JSON. Useful for SOAP leftovers, RSS, and mixed API stacks. XML is parsed with the browser DOMParser so payloads stay on the device.
JSON ↔ CSV
Turn an array of JSON objects into CSV, or parse CSV headers into JSON objects. Quote-aware parsing runs in the tab so spreadsheets of IDs and emails are not uploaded to a conversion service.
JSON to SQL
Turn a JSON object or array of objects into SQL INSERT statements. Set a table name, copy the query, and keep rows on the device instead of pasting fixtures into a hosted converter.
CSV ↔ TSV
Convert comma-separated values to tab-separated values and back, preserving quoted fields. A small delimiter swap for dumps you would rather not paste into a spreadsheet SaaS.
