Developer utilities for JSON, JWT, regex, SQL, and encoding tasks

Developer Tools contains 20 individually documented tools. The group covers formatting, encoding, decoding, simplified data conversion, timestamps, number bases, UUID batches, regex checks, and cron presets.

Pages are grouped around syntax inspection, text encoding, structured-data conversion, time/base conversion, and developer identifier helpers.

Choose the page matching the actual input grammar: strict JSON, simplified CSV/YAML, JavaScript regex, URL component encoding, Base64 text, or integer base conversion.

Formatting tools preserve a representation, while converters change it. JWT Decoder only reads claims; it does not verify a signature. SQL Formatter adds line breaks but does not parse a dialect.

A practical sequence is format or decode a sample, review types and errors, then validate the result in the destination parser or runtime.

These tools run in the browser, but users should still avoid live secrets because clipboard history, screenshots, extensions, and the destination application are outside the page’s control.

Several parsers intentionally support only subsets, JavaScript Number is not arbitrary precision, and browser regex, Unicode, date, and encoding behavior can affect results.
