DigitalToolPad
dev-tools
A suite of modern developer utilities (YAML, JSON, Markdown, diff, regex, converters and a lot more) that run entirely in-browser with no data tracking

What to expect from an ideal product
- Access JSON validation and formatting tools directly in your web browser without downloading or installing any applications
- Copy and paste your JSON data into the online tool to instantly check for syntax errors and proper structure
- Format messy or minified JSON code with proper indentation and spacing using the built-in prettifier
- Validate JSON against standards and get clear error messages pointing to exactly what needs fixing
- Keep your data private since all processing happens locally in your browser with no uploads to external servers
