Online Excel editor

Update cells, formulas and worksheet formatting

Use the spreadsheet editor to update a budget, enter values or check a calculation. Select a cell to enter text or a formula, then review number formats, column widths and other sheets. Choose XLSX when workbook structure and formatting matter.

Supported files and limits

Input formats

XLSX, XLS, ODS, CSV

Download format

XLSX / CSV

Input file limit

100 MB

XLSX, XLS and ODS workbooks can be opened and download as XLSX. CSV files are also supported and save as CSV, which does not preserve workbook formatting or multiple sheets. Individual input files must be no larger than 100 MB.

Open. Edit. Take it with you.

1. 1

   Choose a file

   Open the editor and drop a local Office file into the workspace. You can also create a blank document, workbook or presentation.

2. 2

   Make your changes

   The editor loads in your browser. The first launch downloads its resources and may take a little longer.

3. 3

   Download your copy

   Choose Save to device, then check the downloaded file. Your original file is not overwritten by the website.

Before opening a file

Use an up-to-date desktop browser and keep your original file. The first visit loads a substantial editor engine and fonts; opening or exporting may take longer on a slow connection. After it loads, document processing happens on your device. There is no account, shared cloud drive or real-time collaboration.

Will a CSV file keep formulas and formatting?

CSV is a text table, not a full workbook. It does not preserve cell styles, charts, multiple sheets or workbook formula behavior. CSV inputs save as CSV here; use an XLSX input or start a new spreadsheet when you need an XLSX workbook.

Will every file look exactly the same?

Not always. Complex layouts, unsupported fonts, embedded objects and advanced Office features may differ. Macros are not executed. Review the exported file before sharing important work.
