Chat with your CSV.
Ask your spreadsheet anything.
Drop in a CSV or Excel file and ask questions in plain English. Tablize does the analysis, draws the chart, and explains what it found — no formulas, no pivot tables. And unlike a chat window, the answer sticks around.
Drop it in, ask away
Upload
CSV, Excel, JSON, Parquet, or SQLite. The agent reads the columns and infers types automatically.
Ask
"What's my best month?" "Which customers churned?" The agent analyzes, charts, and explains — in plain English.
Keep
Save the analysis as a report or dashboard, or schedule it to rerun on next month's file automatically.
More than a one-shot answer
ChatGPT with a CSV is great for a quick question. Tablize is what you reach for when the question comes back — when you want the analysis to persist, run on a schedule, or move from a file to your real database. See the side-by-side on the Tablize vs ChatGPT + CSV page.
Your file and analyses stay in a workspace — no re-uploading the same CSV next week.

Frequently asked
What file types can I upload?
CSV, Excel (XLSX), JSON, Parquet, and SQLite. Drop the file in and the agent infers the schema automatically — no setup.
Do I need to write formulas or code?
No. Ask in plain English and the agent does the analysis — pivots, joins, charts, stats — and explains the result. You never touch a SUMIFS or a pivot table.
How is this different from ChatGPT with a CSV?
ChatGPT gives a one-shot answer and forgets your file next session. Tablize keeps the analysis, reruns it on a schedule, connects to your real database when you outgrow files, and turns answers into dashboards or watchers. See the full comparison on our ChatGPT + CSV page.
Can it handle large files?
Yes — files load into a real columnar store, so analysis stays fast well past the size where a chat tool would choke or truncate.
What happens to my data?
On Free, sessions are ephemeral and nothing is retained. On Plus and above your workspace persists your files and analyses. Your data is never used to train models.
