JSON file comparison

Allows comparing two JSON files word by word. Displays differences in values and keys. Processes data client-side.

Who is this solution for?

  • Developers: Allows comparing two JSON files word by word; highlights differences in keys and values; processes data client-side, speeding up iterations and simplifying debugging.
  • UI/UX Specialists: Enables quick identification of structure and content changes in JSON files; differences in values and keys are clearly marked; everything runs locally in the browser without sending data to a server.
  • Administrators: Helps verify configurations and settings stored as JSON; shows differences in keys and values and operates locally in the browser, reducing the risk of data leakage.
  • Anyone who manages access to data on NTFS file systems.

Solution

A lightweight in‑browser JSON diff tool — compares two files word by word, detects differences in keys and values, and processes data client‑side for privacy and speed.

What the tool offers

  • Word‑by‑word comparison: Highlights changes in strings and values at the word level, making it easy to spot subtle differences.
  • Structure and key differences: Marks added, removed and moved keys and shows differences in types and values.
  • Client‑side processing: All analysis runs locally in the browser — data is not sent to a server, improving privacy and responsiveness.
  • Clear visualization: Side‑by‑side diff view, colored highlights and concise summaries for quick assessment.
  • Drag‑n‑drop Drag and drop JSON files directly into the UI: multi‑file support, basic type and size validation, content preview before compare and a 'Choose file' fallback for older browsers.
  • Desktop app integration: Can be packaged as a desktop application (Electron or Flutter Desktop) with direct filesystem access, native drag‑and‑drop from desktop, clipboard import, offline mode, local report export and optional CI/CD/update integration.
