JSON DiffCompare two JSON documents and highlight the differences.Open tool Text DiffLine-by-line diff for any two text inputs.Open tool
Both show you what changed between two documents, but they 'see' differently. JSON Diff understands structure — it compares keys and values, so a reformatted or re-keyed object doesn't read as a change. Text Diff compares line by line, format-agnostic, for any text at all. Pick by what you're comparing: structured data or raw text.
Use JSON Diff when
- You're comparing two JSON documents — configs, payloads, API responses.
- You want a semantic diff: key/value changes, not whitespace or key-order noise.
- The two versions might be formatted differently but you only care about the data.
- You need to spot an added, removed, or changed field in a nested structure.
Use Text Diff when
- You're comparing non-JSON text — logs, markdown, code, env files, SQL.
- You want a line-by-line diff with additions and removals highlighted.
- The format isn't JSON, or you care about the exact lines as written.
- You want to ignore case or whitespace differences with a toggle.
Side by side
| JSON Diff | Text Diff | |
|---|---|---|
| Primary job | Semantic diff of two JSON documents | Line-by-line diff of any two texts |
| Understands | JSON structure — keys, values, nesting | Plain lines, any format |
| Whitespace / key-order changes | Ignored — data only | Shown (unless toggled off) |
| Works on non-JSON | No — JSON only | Yes — anything textual |
| Typical input | Configs, payloads, API responses | Logs, code, markdown, env, SQL |
| Runs 100% locally | Yes | Yes |
under the hood
A useful habit: if two JSON files diff 'noisy' as text, run them through the Formatter first, or just use JSON Diff and let it compare meaning instead of characters.
bottom line
If both sides are JSON and you care about the data, use JSON Diff — it won't shout about re-indenting or re-ordering keys. For everything else, or when the exact lines matter, use Text Diff.
