Save your Excel spreadsheet as an Excel workbook (.xls or .xlsx).
In Microsoft Excel:
- Go to File.
- Choose Save as.
- Name your file and save it somewhere retrievable.
- Open up a blank Google Sheet.
- Go to File > Open. (Or press Cmd + O.)
- Drag the Excel file into the gray box or select the file from your computer.
Once you open your Excel file into Google Sheets, it will automatically be converted to the Google Sheets format. Look it over for any formatting errors, but, generally, the conversion works very well.
Do I need to save the new Google Sheets file?
Nope. By default, Google saves the file with the rest of your Google spreadsheets and in your Google Drive. The file is now sharable and viewable to anyone using Google Sheets.
