What is Status202?
Status202 is a collection of privacy-first developer tools that run entirely inside your browser. Every tool on this site — JSON formatters, CSV converters, XML parsers, Base64 encoders, regex testers, and more — processes your data locally using your device's CPU and RAM. Nothing is uploaded to a server. Nothing is logged. Nothing is stored. Your data never leaves your machine.
The site was built after a colleague was fired for pasting an API response containing customer records into a popular online JSON formatter. The tool logged everything server-side — the terms of service said so, buried deep in a privacy policy nobody reads. An IT audit found it, and he was let go that afternoon. He wasn't careless. He was a good developer doing a routine task that hundreds of thousands of developers do every day without thinking twice. Security researchers at watchTowr have documented similar data collection practices in widely-used online developer tools, confirming this is a systemic problem, not an isolated incident.
The privacy guarantee here works differently from most tools. When you click Format or Transform, your browser's JavaScript engine does the work — the same engine running this web page. The data flows from the input panel into a local function, is processed in memory, and the result is written to the output panel. There is no network request involved. You can verify this yourself: open DevTools (F12), go to the Network tab, paste something sensitive, and watch. You will see zero outbound requests carrying your data. That is the only privacy guarantee worth trusting — one you can verify yourself, not one you have to take on faith.
Status202 is for developers who work with sensitive data daily: API responses containing PII, database exports with customer records, JWT tokens with session credentials, server logs with internal infrastructure details, and configuration files with API keys. It is also for security-conscious teams whose data handling policies prohibit pasting sensitive data into external services. No account is required. No usage limits. Every tool is free, forever.

A colleague got fired for using a tool like this.
He pasted an API response into a random formatter on a Monday morning. The tool logged it. IT found it three weeks later. He was let go that afternoon.
That's why every tool here runs inside your browser. Nothing is ever sent to a server. Here's our guarantee:
Zero Server Processing
When you click "Transform", the computation happens directly on your machine using JavaScript and WebAssembly. No files are ever uploaded.
Zero Data Retention
Because no data touches a server, there are no databases, no logs, and no "delete after 24 hours" promises. Once you close the tab, your data is gone forever.
