## About

JSON strings must escape a small set of characters: the double quote, the backslash, and the control characters (U+0000 to U+001F). Everything else may appear literally.

This tool implements the standard JSON escaping rules from RFC 8259. The "escape" direction converts a raw string into a JSON-safe form (the content you would put between double quotes). The "unescape" direction parses a JSON string literal back to its raw bytes.

## How to use

1. **Pick the direction** — Escape raw → JSON or Unescape JSON → raw. Both directions round-trip cleanly for any valid input.
2. **Paste the input** — For escape, paste any string (control characters allowed). For unescape, paste the JSON-quoted content (without the surrounding quotes).
3. **Copy the output** — Use the escaped form inside a JSON config or template. Use the raw form to inspect what a stored string actually contains.

## FAQ

### Does this also parse JSON objects?

No — it only escapes / unescapes the value of a string literal. To format or validate whole JSON documents, use the JSON Formatter and JSON Validator tools.

### Are forward slashes escaped?

By default, no. JSON allows "/" inside strings (the "\/" escape is optional). The unescape function accepts both forms.

### Are unicode escapes supported?

Yes. \uXXXX is produced for control characters on escape and parsed back to the original code point on unescape.
