Format & Minify
JSON Formatter
Uses the browser's native JSON API to format and minify, with optional key sorting and custom indentation. Everything runs locally.
Format & Minify
JSON Formatter / JSON Key Sorter
Formatting changes whitespace and indentation only, preserving key order; sorting recursively reorders keys at every level (including objects inside arrays) and fixes indentation at two spaces. Use formatting to see structure, sorting to remove "order-only" noise.
| JSON Formatter | JSON Key Sorter | |
|---|---|---|
| Touches indentation | Yes, width and tabs selectable | Yes, fixed at two spaces |
| Changes key order | No, preserved as-is | Yes, recursively through objects and arrays |
| Output already formatted | Yes | Yes — sorting emits indented JSON |
| Typical use | Expand a minified one-liner | Check whether two responses differ only in field order |
Format & Minify
JSON Key Sorter
Recursively sorts every JSON key in ascending order, including nested objects and arrays. Everything runs locally.
Format & Minify
When to use JSON Formatter
- Debugging an API response and you want the nesting visible.
- The field order from the server matters — in some APIs it does.
- You only want it readable, with no comparison planned.
When to use JSON Key Sorter
- Two payloads are equal but their keys came back in different orders, so the diff is pure noise.
- Normalising a config file so later edits only show real changes.
- Comparing two objects line by line.
Verdict
After sorting you do not format again — the sorter already emits indented JSON. Formatting, in the other direction, never removes order noise.
