Developer and text tools

Format structured text, inspect strings and work with encodings or checksums. Review the tool’s input and output before using the result in a project.

Choose the right workflow

Formatting JSON improves readability but does not validate your application’s data schema.
Base64 is an encoding, not encryption. Do not use it to protect secrets.
Regex engines can behave differently. Check the engine and supported flags before copying a pattern into another runtime.
