About these tools
Use focused developer utilities to format, validate, encode, decode, inspect, and transform common data formats. The tools are designed for quick debugging and everyday engineering workflows without sending pasted payloads or files to a processing server.
Client-side processing is useful for convenience and privacy, but you should still avoid pasting production secrets, private keys, access tokens, or regulated data into any browser page unless your organization permits it.
What you can do
- Data formatting and conversion
- Token, hash, and identifier utilities
- Regex, cron, timestamp, and URL tools
- Network and subnet calculations
Common ways to use this category
