Are formulas evaluated?

We show the cached cell values stored in the file (what Calc last computed). Formulas are not re-evaluated in the browser.

Will styling carry over?

The grid is a fast tabular view, so colour fills and borders are not preserved — values, numeric alignment, and dates are. For pixel-perfect styling, open the file in LibreOffice.

No. The .ods is parsed entirely in your browser. Nothing is sent to any server.

About ODS

OpenDocument Spreadsheet (LibreOffice Calc).

ODS is the OpenDocument spreadsheet format used by LibreOffice Calc, Apache OpenOffice, and Collabora. It's a ZIP of XML parts — content, styles, settings — with one table per worksheet. SheetJS reads ODS natively, so this viewer surfaces each sheet as a tab and renders cell values in a fast, scrollable grid with column letters and row numbers. Filter narrows the visible rows on the active sheet. Workbooks open instantly and never leave your browser.
