Generating a CSV String in Python on Zapier

Encountering an error on Zapier when creating a CSV string with Python. My revised code below uses different variable and function names. Any suggestions?

import io
import csv

buffer_text = io.StringIO()
columns = ['name', 'surname']
creator = csv.DictWriter(buffer_text, fieldnames=columns)
creator.writeheader()
creator.writerow({'name': 'Alice', 'surname': 'Smith'})

result = buffer_text.getvalue()
return result

The code looks correct and I had a similar challenge before. I ended up testing a simplified version of the script outside of Zapier and everything worked fine locally. I discovered that sometimes Zapier’s Python environment handles StringIO differently or expects a particular output format. I experimented by carefully checking the print versus return outputs and eventually used a workaround with reusable functions formatting the CSV text. Reviewing platform documentation on how outputs are parsed can sometimes reveal platform-specific quirks that you might need to handle.

I’ve run into a similar issue when working with CSV generation in Zapier’s Python environment. In my case, even though the code appeared fine locally, I noticed that slight differences in the way Zapier parsed the output were causing errors. After some debugging, I experimented with buffering the output and ensuring that nothing else was printed when returning the value, which helped isolate the CSV content. It was also useful to double-check the type and encoding of the returned string. Reviewing the platform’s documentation on output handling provided additional insights that guided my troubleshooting process.
