CVReviewed by Challenging Voice Editorial · Updated Sep 2026How we rate ↗
AskCSV lets users analyze CSV and TSV files by asking business questions in plain English, receiving calculated results and charts back – with all processing happening locally on the user’s own device rather than in the cloud.
Natural language queries convert into SQL automatically via a local AI model, executed through DuckDB integration to produce results and chart visualizations of trends and comparisons. The on-device AI model is about 1.8 GB, downloading once and caching locally for future sessions so file data never leaves the browser. A Pro-only feature combines two files for multi-file analysis.
AskCSV targets business analysts and non-technical users wanting quick CSV insights without SQL knowledge or data-privacy concerns about cloud uploads. Free: 10 successful analyses monthly, no account required. Pro: $5/month, unlimited analyses, export capabilities, two-file combining.
