Need to see what changed between two configs, SQL queries, or JSON responses? A text compare tool highlights every added and removed line — faster than scrolling two files side by side.
When to use text compare
- Config drift — staging vs production
application.yml - SQL refactors — old query vs optimized version
- API changes — JSON response before and after a deploy
- Code review — paste two snippets from a PR
- Log diff — error output before and after a fix
Compare text in your browser
The VyomaStack Text Compare tool runs 100% locally:
1. Paste original text in the left panel
2. Paste modified text in the right panel
3. See the diff update live — green for added, red for removed
4. Switch between side-by-side and unified views
5. Click Copy diff for a +/- unified patch
Format before you diff
Messy formatting hides real changes. Use the per-side buttons:
- Format SQL — beautify queries before comparing (pairs with SQL Formatter)
- Format JSON — prettify API payloads before comparing (pairs with JSON Formatter)
Same logic, different indentation — no longer shows as a false diff.
Diff options
| Option | Use when |
| Ignore whitespace | Indentation differs but content is the same |
| Ignore case | SELECT vs select should match |
| Side by side | Scanning two versions in parallel |
| Unified | Pasting a patch into chat or a ticket |
Text compare vs diffchecker.com
Generic diff sites work for plain text. VyomaStack adds SQL and JSON formatting in the same workspace as your other dev tools — one tab for format, compare, and explain.
Tips
- For large files, compare sections incrementally
- Redact secrets before pasting production configs anywhere
- Pair with Hash Generator to fingerprint files before and after deploy
