Online JSON Tools

Format compressed JSON strings into indented, readable form while validating JSON structure. Supports custom indent width and space/tab switching.

Remove all unnecessary whitespace and line breaks from JSON, compressing data to a single line to reduce size.

Convert JSONC (JSON with comments, e.g. tsconfig.json) or JSON5 (relaxed JSON syntax) to standard JSON.

Convert between JSON and YAML formats in both directions. Useful for config file migration and CI/CD pipeline debugging.

Convert JSON arrays to CSV tables, or restore CSV back to JSON object arrays. Supports custom delimiters and field mapping.

Convert JSON data into structured XML documents. Useful for interfacing with SOAP services or legacy XML APIs.

Compare two JSON datasets line by line, highlighting additions, deletions, and modifications. Great for version comparison and API response change debugging.

Escape special characters in JSON strings (quotes, backslashes, etc.) to generate string literals that can be directly embedded in code.

Restore escaped JSON strings to their normal format by removing extra escape characters.

Use XPath-style JSONPath expressions to precisely locate and extract data in complex JSON. Supports wildcards, filters, and recursive descent.

Validate JSON data structure and types against JSON Schema specifications. Supports Draft-07/2019-09/2020-12 with detailed error reports.

Interactively browse large JSON data in a collapsible tree structure. Supports node expand/collapse, search, and path copying.

Sort JSON object keys alphabetically and deduplicate array elements. Gives JSON data consistent ordering for version control and manual comparison.

Quickly generate random mock data from predefined templates or real-time edited skeletons. Supports custom field types, array lengths, and value ranges.
