Free, browser-based utilities for everyday developer workflows

Help & Contact

Use this page to choose the right tool, report issues, or suggest new workflows to cover.

Start here if you are unsure which tool you need

You pasted structured data

Start with JSON Formatter, JSON / YAML Converter, or Schema Inspector depending on whether you want readability, conversion, or structure.

You pasted tokens, headers, or request details

Try JWT Decoder, HTTP Headers Parser, or cURL Converter first. These are the most common entry points for API debugging.

You pasted rows, IDs, or spreadsheet columns

Use List Comparator, CSV Viewer, or SQL IN Clause Builder depending on whether you need comparison, cleanup, or query-ready output.

How to report a bug well

The fastest way to get a useful fix is to send a short, reproducible report. Include the page URL, browser, what you pasted, what you expected, and what happened instead. If the input is sensitive, replace it with a safe sample that still reproduces the problem.

  • Tool URL or page name
  • Browser and device
  • Minimal sample input
  • Expected output
  • Actual output or error message
Feature requests and new tool ideas

New tools are most useful when they solve a repeated workflow, not a one-off edge case. When requesting a tool, explain the recurring job you are trying to speed up: what format you start with, what output you need, and why existing tools are not enough. That makes it easier to design a page with real value instead of another generic converter.

Frequently asked questions
Does the site upload my data?
Most tools process data locally in your browser. Review the Privacy Policy for the exact details.
Can you review my private production file by email?
Do not send private production data. If you need help, send a redacted or synthetic sample instead.
Why does a tool behave differently across browsers?
Clipboard permissions, local file APIs, and large in-browser payloads can vary between browsers. Include browser details when reporting the issue.
Where should I start if I just landed on the site?
Start with the Guides page for routing advice or the Use cases page if you already know the task you are trying to complete.

The inbox is used for bug reports, workflow suggestions, and questions about how a tool behaves. Messages with reproducible detail are easier to act on than broad reports.
