Before you rely on the result
A failed import is not always a damaged file. Viewer limitations, inaccessible resources or ambiguous coordinate values may require manual work. Repairs do not guarantee acceptance by every GIS tool.
Choose the right approach
App, built-in tool or another workflow?
Written by the developer of this app. Choose according to your task; a built-in tool may be enough.
Manual XML editing
Suitable when you understand the format and need a specific change; keep a backup.
KML Doctor
Provides issue locations, reviewable repairs, batch checks and a separate output copy.
Viewer import
Shows whether a file works in that viewer, but is not a complete validation of every KML feature.
A practical check before you share
If a Placemark refers to a missing style ID, review the reference and available styles. Do not substitute an unrelated style automatically. Re-check the saved copy and inspect the map.
