Get Insights From CSV by Asking Questions

Get insights from CSV without the spreadsheet busywork

If you have ever stared at a CSV with thousands of rows and thought "there's a story in here somewhere," you know the problem. The data is right in front of you, but pulling out the numbers that matter usually means pivot tables, memorized formulas, or exporting everything into a tool you do not fully trust.

AskCSV skips all of that. Open a CSV or Excel file, ask a question the way you would ask a coworker, and the answer comes back as a number, a table, a chart, or a KPI figure. No sign-up is needed to try it.

Why a fast feedback loop matters

A shorter analysis loop changes how you work with data. When asking another question takes less effort than rebuilding a spreadsheet report, you explore more freely. You notice a strange spike and ask "which week caused that?" You spot an outlier and ask "show me the top 10 customers by revenue." Each answer leads to the next question.

AskCSV is built for that rhythm: ask, see, refine, repeat — with the SQL visible underneath each result so a surprising number can be checked instead of trusted.

How the answers are produced

1. Your file opens in the browser. It is kept in this site's storage for your account or guest session; the file is not uploaded.
2. Your question becomes a query. The AI proposes a read-only SELECT from the columns you chose to share, their types, and a few sample rows.
3. The query runs on the whole file. DuckDB executes it in your browser, over every matching row rather than a sample.
4. The numbers are computed, not written. Totals, counts, shares, and trends come from the query result in code; the AI explains the result, and the generated SQL is displayed with the chart.

AskCSV keeps what the AI sees to a minimum: the AI provider gets only the question, the file's name and row count, the names and types of the columns you chose to share, up to 10 sample rows, up to 100 rows of each query result plus summary figures, and the earlier messages in the chat — never the file itself.

How to get insights from CSV

1. Open the app. Head to the homepage — no sign-up, email, or credit card required to try it.
2. Open a CSV or Excel file, or paste delimited rows.
3. Ask in plain English. Type something like "What were total sales by month?" or "Which regions are trending down?"
4. Read the answer. You get a summary, calculated numbers, and a chart where a visual helps.
5. Keep going. Ask a follow-up to slice it a different way or drill into a segment.

That is the whole loop. No setup, no configuration, no manual.

What you can ask

• Quick summaries — averages, totals, counts, and min/max across a column
• Trends over time — month-over-month growth, seasonality, or a sudden dip
• Rankings — top products, biggest accounts, worst-performing campaigns
• Comparisons — this region versus that one, before versus after
• Distributions — histograms of order amounts, and the values sitting outside the norm

Because the AI understands plain language, you do not need to know which formula or query would produce the result. You describe the outcome you want and check the SQL that produced it.

Limits and data handling

Guests get $0.25 of credits to try it (about 5 answers). Sign in with Google to subscribe; your file stays in this browser either way. A $5/month subscription includes $5 of usage each month (about 100 answers); add credits from $10 (about 200 answers) when you need more. A typical answer costs about $0.05. Credits pay only for the tokens the AI reads and writes, so a request refused before the AI runs costs nothing.

Guest credits expire 7 days after they are issued. Files and chats stay in this browser until you delete them or clear the site's data. AskCSV analyzes opened files only — it does not connect to your database — and AI answers can be wrong, which is why the SQL is shown.

Built for people, not analysts

You do not need to be technical to get insights from a CSV. If you can describe what you are curious about, you can ask for an answer. Marketers check campaign performance, operations leads watch inventory, and founders review signups — all from the same simple box, without learning formulas or SQL.

Open the app, open a file you are authorized to analyze, and ask your first question.
