Why this tool is useful
Review a Google Earth export, field survey, map annotation set or delivery plan for malformed locations and hidden network dependencies before sharing it.

Private KML Map and Placemark File Auditor
Inspect a saved KML map for documents, folders, placemarks, geometry, invalid coordinates, duplicate identifiers and inert external references without opening network links or exposing the map to a server.
Ready. Your working data stays in this browser.
Files stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
The browser parses bounded KML as inert XML, walks its folder hierarchy and validates Point, LineString, Polygon, MultiGeometry and gx:Track coordinates.
Practical example
Audit a project map to locate a repeated placemark ID, one out-of-range latitude and a NetworkLink that would otherwise depend on a remote server.
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.
