Getting started
From a messy sheet to clean data in five steps.
- Open a sheet. Choose Try a sample on the start screen, or upload an Excel (XLSX) or CSV file. Your formatting is kept.
- Look around. The grid shows your data with its colours, merged cells and number formats. Sort and filter from the column header menu without changing the data.
- Ask the assistant. Open the Assistant tab and describe what is wrong or what you want, for example "which columns have mixed types?" or "turn the Weight column into numbers".
- Review the preview. A proposal shows exactly which rows would change, before and after. Nothing is applied until you click Apply. Discard drops it.
- Undo or export. Every applied change appears in History and can be undone. Save a copy as XLSX or CSV, or export structured JSON.
The assistant can also suggest fixes it finds on its own, such as stray spaces or numbers stored as text. These go through the same preview.
