URL & Query-Parameter API
Every tool is an addressable service. You can prefill any input or option, auto-run the tool, and deep-link to a result — entirely client-side, with nothing sent to a server. Great for docs, bookmarks and quick workflows.
Universal parameters
?<id>=value— set any control on the page by its element id. Checkboxes accept1/0. Example: the EMI calculator takes?p=3000000&r=8.5&n=20.?input=…— fill the tool's primary input (the big text box). URL-encode it.?url=…— fetch a remote file from your browser into the primary input. Note: our privacy Content-Security-Policy restricts network requests, and the other site's CORS rules also apply — so cross-origin fetches are usually blocked. When that happens, download the file and use the Upload file option (read locally, nothing uploaded).?run=true— click the tool's primary action (for tools that don't compute live).#s=…— a compressed snapshot of every field, used automatically by “Copy shareable link” when the state is large. It lives in the URL fragment, which browsers never send to any server — so share links stay private.
Examples
/formatters/json-formatter/?input=%7B%22a%22%3A1%7D&run=true/cryptography/base64-encoder-decoder/?input=Hello&run=true/converters/decimal-to-binary-converter/?n-input=500/calculators/emi-calculator/?p=3000000&r=8.5&n=20
Shareable links
Every tool page has a “Copy shareable link” button that captures your current inputs and options into a URL. Small states use readable query parameters; large ones are deflate-compressed into the #s= fragment. Either way the data is encoded in the link and never uploaded.
Bookmarklet
Drag a one-click bookmarklet to your bookmarks bar. This one formats the JSON at whatever URL you're viewing:
javascript:(function(){window.open('https://www.codingsetu.com/formatters/json-formatter/?run=true&url='+encodeURIComponent(location.href))})();
Privacy
The API changes nothing about how tools handle data: everything runs in your browser. The ?url= fetch is made directly by your browser, and #s= share state never leaves the page. See the privacy policy.
