CSV data analysis in one browser tab.
Go from a raw CSV to a defensible answer and a report without setting up a workbook, notebook, database, or account. Ask in plain English, inspect every formula and evidence row, or switch to SQL and dashboards when you need more control.
Build once, rerun on the next export.
Ask for a total, ranking, trend, filter, or quality check in plain English. Each deterministic answer shows its exact formula and evidence. Pin the useful findings, reorder them, add context, and save the ordered questions as a reusable analysis recipe. Next week, choose that recipe before loading the new file and rebuild the report locally.
Ask questions in SQL.
Real SQL against your CSV — SELECT, WHERE with AND/OR, ORDER BY, LIMIT. No database, no schema definition, no upload. The query engine runs locally in your browser.
Auto-summaries on every CSV.
Every tool page shows an Insight Strip below the output — KPIs (rows, columns, totals, missing values), three deterministic observations (concentration, trend, outliers, correlations), and a suggested chart. No AI, no API call.
Chain operations into a reproducible workflow.
Validate, clean, query, and export — in any sequence. Re-runs instantly as you change parameters. Useful for iterating on what you're really looking for.
Build an interactive dashboard.
Auto-generated KPIs, time-series chart with forecast, category breakdowns, geographic bubble map for country/region columns, scatter plot with correlation, and a sortable Excel-like data table.
Common questions.
-
·
Is this a replacement for Excel pivot tables?
For many cases, yes — the dashboard's pivot mode covers row × column × value crosstabs with sum/avg/count. For very complex multi-pivot workbooks, Excel is still better.
-
·
Can it handle multiple files?
Yes. Use CSV Join for inner, left, right, or full outer joins, CSV Merge for a compact key-based merge, or CSV Compare for side-by-side metrics. The Ask CSV workspace analyzes one combined dataset at a time.
-
·
Can I repeat the same report with a new CSV?
Yes. Save an Ask CSV brief as an analysis recipe. The recipe keeps only the report framing and ordered questions, then recalculates them against the next compatible file. It never stores the old CSV or its answers.

Where does the data go?
Nowhere — analysis runs in your browser. Verify in DevTools → Network.
