Drop a spreadsheet here

Excel files open with every sheet on its own tab. CSV delimiters are detected for you.

Search every column, combine conditions with AND and OR, and pick values from an Excel-style list.

Choose rows, columns and a total, and switch grand totals on or off.

Download xlsx or csv of the current view or the full sheet, and pdf for pivot tables.

Supports xlsx, xls, csv and tsv. Files stay in memory and are discarded when you close them.
