Question 1

What file types can I edit?

Accepted Answer

You can open spreadsheet files (XLSX/XLS), edit cells, insert/delete rows or columns, and export as XLSX or CSV.

Question 2

How do I edit a specific cell (like B12)?

Accepted Answer

Click a cell in the table or type a reference like A1/B12, edit the value field, then press Apply.

Question 3

Can I export only a selection?

Accepted Answer

Yes. Select a range and use “Copy selection as CSV” or download CSV for sharing with other apps.

Question 4

Are formulas and styles preserved?

Accepted Answer

Basic data editing works best. Complex formulas, formatting, and charts may not fully round-trip in a lightweight browser editor—always verify after export.

Question 5

Is it private and offline-friendly?

Accepted Answer

Yes. Files are processed locally in your browser and are not uploaded. After the first load, it can often work offline.
