Popular JSON Tools

Pretty printing XML means adding consistent indentation and line breaks to a flat or minified XML document so it's easy for humans to read. Without pretty printing, even a small XML document with just a few nested elements becomes difficult to understand when it's all on one line or using inconsistent spacing.

JSON Viewer Pro's XML pretty printer parses your XML using the browser's native DOMParser and re-serialises it with clean, consistent indentation. You can choose between 2-space, 4-space, or tab indentation. The result is immediately available in the Monaco editor with XML syntax highlighting, ready to copy or download.

All processing runs locally in your browser with no server involvement. This makes JSON Viewer Pro safe to use with any XML content including configuration files, API payloads, and documents that may contain sensitive values.
