Error: Open of file "filename.kmz" failed: Parse error at line x, column y : not well-formed (invalid token)

Error Message

After converting a layer or map document to a KMZ file in ArcMap using the Layer To KML tool, the file cannot be opened in Google Earth, and a parse error regarding an invalid token is returned.


This issue occurs because the layer name or one or more of the attribute fields are formatted incorrectly. There may be invalid characters such as "<" and ">" in the fields or the layer name. Because KML is an XML-based format, it recognizes these symbols as HTML tags. This causes Google Earth to be unable to read the field data.

Solution or Workaround

Before converting the layer or the map document to KML, rename or remove invalid characters from the field.
