Developer Utilities
Format JSON, decode tokens, convert CSV and test regular expressions.
What are Developer Utilities?
Developer utilities are small tools for jobs that come up again and again: reading a block of JSON, checking what is inside a token, turning a spreadsheet into data, or trying out a pattern.
They run in your browser, so the data you paste is not uploaded.
What you will find in Developer Utilities
Includes a JSON formatter and validator, a JWT decoder, CSV to JSON and JSON to CSV converters, and a regex tester.
How to use these tools
- Choose the utility you need.
- Paste your data or pattern.
- Copy the result.
Did you know?
- JSON became the most common format for web data because it is simple and every language can read it.
- The payload of a JSON Web Token is only encoded, not encrypted, so anyone with the token can read it.
