Backend Developer Tools
SQL formatter, regex tester, JSON/XML/YAML formatter, timestamp converter, hash generator, JWT decoder โ essential online toolkit for backend developers and database administrators.
How to use backend tools
Backend developer tools combine data formatting, API debugging, token inspection, timestamp conversion, SQL cleanup, and regular expression checks in one browser-based workspace.
Common use cases
- Format API payloads before sending test requests.
- Check JWT payloads, hashes, UUIDs, and timestamps during backend debugging.
- Clean SQL, JSON, YAML, XML, or regex snippets before sharing them.
Recommended workflow
Move from raw request data to formatted output, inspect the value that caused the issue, and then copy only the cleaned test case back into your API client, issue tracker, or code review.
