Fast CSV

1. How fast is it, really?

It's incredibly fast. You can start exploring the first 100,000 rows of your CSV in under 3 seconds—no more waiting for the entire file to load. Compared to tools like Excel or Google Sheets that struggle with large files, FastCSV opens them instantly.

2. Who is this for?

FastCSV is a lifesaver for anyone who works with large CSV files: data analysts, developers, marketers, researchers, and students. If you've ever been frustrated by slow-loading spreadsheets, this tool is for you. It handles gigabytes of data with ease, right in your browser.

3. Is it really free?

Yes, 100% free. I built FastCSV to solve a problem I had, and I want to share it with everyone. There are no hidden costs or premium features. If you find it useful, spreading the word is the best way to say thanks!

4. What if I don't know SQL?

No problem! FastCSV includes an AI-powered chat assistant. To protect your privacy, we only send your table's structure (column names and data types) to the AI—never your actual data. Your request goes directly from your browser to the AI provider, with no middle servers. Just describe what you're looking for in plain English, and the AI will write the SQL query for you.
