NotchMindThe Developer Tools page on Home does the small conversions you’d otherwise open a website for. It runs on your Mac; nothing is sent anywhere.
The tools
| Tool | What it does |
|---|---|
| Format JSON | Pretty-prints JSON with indentation. |
| Validate JSON | Tells you whether it’s valid JSON. |
| Minify JSON | Removes the whitespace. |
| Base64 encode / Base64 decode | Converts text to and from Base64 (UTF-8). |
| URL encode / URL decode | Percent-encodes text for URLs, and back. |
| UUID v4 | Makes a new random UUID. |
| Convert color | Converts a hex color or rgb() / rgba() value to other notations. |
| Unix seconds → UTC | Turns a Unix timestamp into a readable UTC date. |
Use it
- Open the notch and swipe to Developer Tools.
- Pick a tool from the menu at the top.
- Paste your input where it says Paste here.
- Press the arrow button. For UUID v4, just press the button.
- Choose Copy result to copy the output.
Clear empties both boxes. Input can be up to 1 MB.
Errors
The page says what’s wrong instead of guessing, for example Enter valid Base64 containing UTF-8 text or Enter Unix seconds between years 0001 and 9999.
