How to parse HTML file content using Python in Zapier automation

I need help extracting data from an HTML file using Python within a Zapier workflow. I have been struggling with this for a while now and tried multiple approaches but nothing seems to work properly.

Here’s what I’m currently attempting:

with open('document.html', 'r') as file_handler:
    html_content = file_handler.read()
    print(html_content)

I’ve been following various online guides and copying code snippets, but I keep running into issues. The file reading part doesn’t seem to function as expected in the Zapier environment. Has anyone successfully implemented HTML file reading in Zapier’s Python code action? What am I missing here?

This happens because Zapier’s Python environment doesn’t work like regular Python when it comes to files. Don’t try to read HTML as a file - treat it as data instead. I’ve hit this same problem before. Zapier wants you to pass HTML content from earlier steps in your workflow. Skip the file handlers completely. Set up your trigger or previous action to give you the HTML as a text variable, then work with that string directly. BeautifulSoup works great for parsing once you’ve got the text. The trick is remembering that Zapier’s Python code runs on workflow data, not filesystem stuff. Just make sure whatever step provides your HTML outputs it as text data your Python step can grab.

for sure! grab the HTML from a prior step in yer Zap. try input_data['html_content'] - it’s the way to go. zapier isn’t like normal python, so ditch the file handling. BeautifulSoup will parse everything smooth once you have the content.

The problem is that Zapier’s Python environment is sandboxed - you can’t access local files like you would in regular Python scripts. You need to get the HTML content through Zapier’s input system instead. Pull the HTML from a previous step in your workflow - maybe a webhook, file download, or another trigger that gives you the HTML as text. Once you’ve got the HTML as a string, BeautifulSoup will parse it just fine. I ran into this same issue when I started using Zapier’s code actions. Just restructure your workflow so the HTML flows through Zapier’s data pipeline instead of trying to read files from disk.
