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

Developer utilities for JSON, JWT, regex, SQL, and encoding tasks Developer utilities are meant for debugging, formatting, and checking small pieces of data during everyday engineering work. Current tools include JSON Formatter, Base64 Encoder/Decoder, JWT Decoder, Regex Tester, SQL Formatter, URL Encoder Decoder, HTML Escape Unescape, JSON to CSV, CSV to JSON, JSON to YAML, YAML to JSON, Timestamp Converter, Unix Time Converter, Base Converter, Decimal to Binary.

Use these tools to format JSON, decode JWTs, test regular expressions, convert Base64, and make SQL easier to read before pasting it into documentation, tickets, or local test fixtures.

Each tool keeps input and output visible together so developers can inspect changes quickly. The pages avoid account systems, project setup, and unrelated dashboards.

Most developer tools run client-side, which is important for payloads, sample tokens, and internal snippets. Sensitive secrets should still be redacted before pasting into any web page.

Start with the tool that matches the exact output you need, then use related links when the task changes. This keeps each page focused while still giving visitors a clear path from one workflow to the next.
