URL & JSON Studio

About

Automatically detect if a browser tab is loading a raw JSON page (by checking the `Content-Type: application/json` header or parsing the page text) and format it instantly.

Color-code different data types (strings, numbers, booleans, nulls, and keys) so the data is easy to scan.

Allow users to click an arrow next to objects `{...}` or arrays `[...]` to collapse or expand them.

Toggle Raw vs. Formatted:** A quick button or shortcut to switch back to the original, unformatted raw text.

Valid JSON Parsing:** Robust error handling. If the JSON is invalid, it shouldn't just crash; it should show a clear error message pointing out the syntax error (e.g., missing comma, trailing comma).

If `parameterValue.length > 50`, split the string by commas `,` and display them as an array of editable inline tags or a clean comma-separated block.

Provide a small "Expand" or "Edit Raw" icon next to it so the user can easily paste or edit the full continuous string in a mini modal text area.

* Each parameter row gets a leading checkbox.
* Unchecking it keeps the key/value pair saved in your UI state but completely strips it from the generated "Live URL" in real-time

 As the user types a new key name, match their input against this array to populate a native HTML `<datalist>` or a custom absolute-positioned dropdown container.

Test / Ping:** Runs a rapid background script `fetch(url, { method: 'HEAD' })` and returns a colored badge (`200 OK` in green, `404` in red).

A single click copies the compiled URL to the clipboard.

Instead of a simple code snippet, this tab features a clean dropdown containing **all 18 code targets** matching your image. Selecting an option converts the live URL into an instantly copyable code snippet block:
