Edit Word and Excel files without an Office subscription: open a docx or xlsx, make your changes and save it again. Everything happens in your own browser — your documents never leave your computer.
Open an Excel file (xlsx, xls, csv or ods), edit the cells in a spreadsheet grid and save it again as .xlsx — no Office needed, 100% in your browser. Formulas are preserved and keep calculating when you open the file in Excel afterwards.
Open a Word file (.docx), edit the text with formatting (bold, italic, headings, find & replace) and save it again as .docx — no Office needed, 100% in your browser. Whatever you don't touch (styles, headers and footers, images) stays unchanged in the file.
