Tool category
Data analysis & spreadsheets
Analyse CSV files, build charts and speed up spreadsheet work.
Data analysis AI evaluates tables, answers questions in plain language and creates charts – with no formulas. You upload your file and simply ask what you want to know. For occasional evaluations the free versions are enough; larger data volumes and recurring reports need more power.
How do I choose the right tool?
- For small, occasional evaluations, the free version is enough.
- For large files, watch the upload and performance limits.
- For recurring reports, a connection to live data pays off.
- Anonymise sensitive data before you upload it.
