Contact Us
We'd love to hear from you. Whether you've found a bug, have an idea for a new tool, want to report a problem with a result, or have a question about how JSONLint.app works, please reach out — your feedback directly shapes the tools we build.
The best way to reach us is by email. We aim to respond to all genuine enquiries within a few business days.
What to include
To help us respond quickly, please include where relevant:
- The tool or page you were using (e.g. JSON Validator, JSON to CSV);
- What you expected to happen and what actually happened;
- Your browser and operating system, for bug reports;
- A small, non-sensitive sample of the input that triggered the issue (never send us confidential data — remember, all processing already happens privately in your own browser).
Feedback & feature requests
JSONLint.app already offers 40+ free tools for working with JSON, and we're always adding more. If there's a converter, validator, or utility you wish existed, tell us — many of our tools started as a single user request.
