Frequently Asked Questions

Why can't I import directly from Google Sheets?+

Modern browsers block direct website-to-website data fetching (CORS policy) for security. The safest and most reliable method is to open your Google Sheet, go to File > Download > Comma Separated Values (.csv), and upload that file here.

My CSV isn't working, what should I do?+

Our tool auto-detects commas, semicolons, and tabs. If it still fails, ensure your file is saved as a standard CSV and has at least two columns with data.

How many sets can I create?+

You can create diagrams with 2 to 8 sets. For 2-3 sets, you get classic overlapping Venn diagrams. For 4+ sets, you get a radial layout.
