Options & Themes

Tailor your JSON Pro experience with flexible customization tools. From font settings to theme management, you're in control of how your workspace looks and feels.

Font Settings

Choose from a variety of font families and adjust font sizes to suit your reading comfort. Whether you prefer compact layouts or spacious readability, the app adapts to your style.

Theme Picker

Instantly switch between 8 preconfigured themes using the intuitive theme selector. Your selection is applied immediately, giving you a seamless visual refresh.

Color Customization

Fine-tune colors for background, text, and tabs using individual color pickers. Click “Apply” to save your changes—this temporarily replaces the default “Edit Themes” button for clarity.

Edit Themes

For advanced users, load the themes.json file into the editor to manually modify or create themes. Save your changes to reflect updates instantly. Note: the active theme cannot be changed via manual edits, and invalid data is flagged automatically.

Pro Tip

Custom themes are stored locally. If you uninstall the app, be sure to save a copy of themes.json to preserve your work.
