- Extensive multi-format conversion (CSV, XML, YAML, Java, C#)
- Built-in side-by-side comparison/diff tool
- Dual-platform availability (iOS and Android)
- Implement node-based editing to simplify mobile data entry
- Add iCloud or SFTP support for professional file management
- Introduce a 'History' feature to match contender Pavel Shcherbakov

Since the last report: The app has pivoted its feature set to emphasize technical depth (JSONPath) while identifying critical gaps in UI modernization and workflow persistence compared to newer competitors.
Bottom line
JSON Tools is a functionally deep utility that wins on technical features like JSONPath and diffing, but is losing ground to competitors with better persistence (History) and more modern UI. To reverse the current ranking decline, the PM must prioritize workflow continuity features and consider a UI refresh to match modern iOS standards.
