Encoding, formatting, and hash generation — the utilities you reach for daily

This category collects the small tasks that come up almost every day while coding — cleaning up JSON, Base64/URL encoding, testing regular expressions, generating hashes and UUIDs — all handled right in your browser. Paste in an internal API response or unreleased code without worrying about it leaving your machine.

Alongside formatters and converters, you'll also find quick-reference dictionaries for things like HTTP status codes and port numbers — handy to bookmark for whenever you need to look something up mid-debugging.

Frequently Asked Questions (FAQ)

Q.Is sensitive data like API keys or JSON payloads sent anywhere?

No. Every tool in this category runs as JavaScript in your browser — whatever you paste in is processed locally and never transmitted to a server.

Q.Could regex test results differ from my actual programming language?

Yes — this tool runs on JavaScript's regex engine, so behavior can differ in detail from engines like PCRE used by other languages.

Q.Can it handle large JSON files?

Very large files may slow down due to browser memory limits, but typical API responses and config files work without issue.

Q.Which hash algorithms are supported?

Common algorithms like MD5, SHA-1, and SHA-256 — you can pick the one you need on the tool page.
