This is what my custom Excel macro is generating (I’m new to programming, so take it easy on me if you notice something big). When I attempt to open the KML file with Google Earth, I get the following message: Open of file “file path” failed: Parse error at line 2, column 454: mismatched tag. This correlates to the /Description tag… What is wrong with this tag? I matches up with it’s corresponding Description tag.

    There are a handful of techniques you can apply to debug and repair a corrupt KML file.

    Basically, the quickest way to validate a KML file is first using your web browser. KML is an XML file so first you can test if it’s a well-formed XML file, which is a prerequisite to it being a valid KML file. Simply rename the KML file adding an .xml file extension then drag the file onto a web browser (Firefox, Chrome, etc.) to validate it. See detailed example here.

    Once those errors are found and fixed then you can try a KML validator that checks if the file is valid KML with respect to the OGC KML Specification and associated XML Schema such as
    the standalone command-line XmlValidator tool.

    In your example, if you run it through a simple XML SAX parser it shows: element type "br" must be terminated by the matching end-tag "</br>" at column 455.

    Error being that <description> element has HTML markup but isn’t escaped with a CDATA block (CDATA is part of the XML standard). To fix this you need to reformat your KML like this:

      <description>
      <![CDATA[
          <b>Project Information</b>
          ...
          <br>
      ]]>
  </description>

    Also, the element has the wrong name (Description vs description). KML is case-sensitive.
