JSON Unescape
Unescape and restore JSON-encoded string literals back into human-readable raw text, resolving quotes, newlines, and unicode escapes.
Quick Answer & Understanding Your Result
A JSON Unescape tool converts escaped JSON string literals back into clean, human-readable raw text, restoring real newlines, quotes, and decoded Unicode glyphs.
Core Unescape Conversions
- Quotes & Slashes: Restores
\"to standard double quotes (") and\\to literal backslashes (\). - Control Sequences: Converts
\ninto real line breaks and\tinto horizontal tabs. - Unicode Characters: Decodes 4-digit hexadecimal escape sequences (e.g.
\u00A9ightarrow©,\u2764ightarrow❤).
Development Applications
- API Payload Inspection: Reading formatted text extracted from string fields in webhook logs or database records.
- Debug & Log Analysis: Converting single-line escaped stack traces into multi-line readable error reports.
Paste your escaped JSON string above to restore it into clean, readable text instantly.
Formula & Calculation Logic
Technical Specification & ASTInverse escape parsing:
- Replaces two-character escape sequences with their native UTF-8 runtime character representations.
Step-by-Step Guide
