Most standard online XML beautifiers fail or freeze your browser tab as soon as a file exceeds 10MB or 20MB.
This happens because traditional web tools load the entire text payload into the active DOM or RAM thread simultaneously. The result? Instant memory leaks.
To solve this, I built a 100% frontend, serverless solution. It handles massive database exports and raw logs directly in the sandbox browser tab without crashing.
Instead of choking the system memory, the tool processes data sequentially:
[Massive XML File] ➡️ [File Stream Reader] ➡️ [Web Worker Parsing & Indentation] ➡️ [IndexedDB Async Queue Cache] ➡️ [Service Worker Interception Download]
