Why this tool is useful
Review a publisher, podcast or migration export before distribution, while keeping unreleased titles and private feed endpoints on the current device.

Private RSS and Atom Feed File Auditor
Inspect a saved RSS 2.0 or Atom feed for entry counts, duplicate identifiers and links, missing titles or dates, enclosure metadata, content markup and structural limits without requesting the feed or any linked resource.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
How it works
A bounded inert tokenizer reads RSS and Atom elements as data, records entry and enclosure facts, and never resolves DTD entities, HTML fragments or linked URLs.
Practical example
Save a feed response as XML, inspect duplicate GUID and alternate-link counts, then fix missing publication dates or enclosure types before publishing a new snapshot.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
