Format and normalize JSON or JSON-like strings in the editor.
Features:
- Flexible parsing: raw JSON, JSON in escaped strings, multi-layer escapes.
- Unicode unescaping: restore \uXXXX and surrogate pairs.
- JSONC tolerant (optional in parser): comments and trailing commas.
- Fast path for small inputs; worker offloading for large/complex cases.
- Honors editor indentation (tabSize/insertSpaces) and EOL.
- Size limit to avoid blocking (configurable).
Command:
- json-format: 格式化 JSON (Default: Ctrl+Alt+J)
Settings:
- json-format.maxInputSizeMB (number, default 2): Max input size in MB. 0 = unlimited.
- json-format.decodeUnicode (boolean, default true): Whether to unescape Unicode sequences.
Usage:
- Select a region or run the command on the whole file. The extension parses, decodes, and formats the JSON.
