- Which indentation should I use?
- 2 spaces is standard in JavaScript/TypeScript ecosystems. 4 spaces is common in Python and Java. Tabs allow each developer to set their preferred visual width. Follow your team's style guide.

What is JSON Beautifier?
A JSON beautifier transforms minified or poorly formatted JSON into a clean, readable format with your choice of indentation style. Unlike a basic formatter that uses a single indentation setting, a beautifier offers multiple options: 2-space indentation (popular in JavaScript and web development), 4-space indentation (common in Python and enterprise environments), and tab indentation (preferred by some teams for accessibility and customizable display width). The beautifier preserves all data integrity while making deeply nested JSON structures easy to navigate. This is particularly useful when working with complex API schemas, deeply nested configuration objects, or large datasets where visual hierarchy is essential for understanding the data structure.
