<h2>What is KML?</h2>

Similarly to XML, KML uses a tag-based structure with nested elements and attributes. </p>
<h2>How to Convert KML to CSV in Python?</h2>
<p class="has-global-color-8-background-color has-background">You can convert a <code>.kml</code> to a <code>.csv</code> file in Python by using the <a rel="noreferrer noopener" href="https://blog.finxter.com/python-beautifulsoup-xml-to-dict-json-dataframe-csv/" data-type="post" data-id="474965" target="_blank">BeautifulSoup</a> and the <code>csv</code> libraries. You use the former to read the XML-structured KML file and the latter to write the CSV file row by row. </p>
<p>Here’s the code example inspired but modified from <a href="https://gist.github.com/mciantyre/32ff2c2d5cd9515c1ee7" data-type="URL" data-id="https://gist.github.com/mciantyre/32ff2c2d5cd9515c1ee7" target="_blank" rel="noreferrer noopener">this</a> GitHub repository. You can copy&paste it in the directory where your KML file resides and change the input and output filenames at the beginning to convert your own KML to a CSV in Python:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="python" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">from bs4 import BeautifulSoup
import csv infile = 'my_file.kml'
outfile = 'my_file.csv' with open(infile, 'r') as f: s = BeautifulSoup(f, 'xml') with open(outfile, 'wb') as csvfile: writer = csv.writer(csvfile) for coords in s.find_all('coordinates'): # Take coordinate string from KML and break it up into [Lat,Lon,Lat,Lon...] to get CSV row space_splits = coords.string.split(" ") row = [] for split in space_splits[1:]: # Note: because of the space between <coordinates>" "-80.123, we slice [1:] comma_split = split.split(',') # lattitude row.append(comma_split[1]) # longitude row.append(comma_split[0]) writer.writerow(row)
</pre>
<h2>Example Conversion</h2>
<p>We use the following <a href="https://developers.google.com/kml/documentation/kml_tut" data-type="URL" data-id="https://developers.google.com/kml/documentation/kml_tut" target="_blank" rel="noreferrer noopener">sample</a> KML file as <code>'my_file.kml'</code>:</p>

[Did you notice that double-clicking on the placemark doesn't cause the viewer to take you anywhere? This is because it is possible to directly author a "placeless placemark".
