Check spelling in Google Spreadsheets
You can now check your spelling in spreadsheets. The tool will go through all the cells on your sheet, highlighting each cell which has a misspelled word in red. Words that might be misspelled in each cell are underlined in red and can be changed by clicking on them and selecting the right spelling.
How to access what’s new:
When editing a spreadsheet, select ‘Tools’, then ‘Check spelling’ to check your sheet. Click ‘Next’ to go to the next cell and once all the cells on one sheet have been checked, you can continue to the next sheet.
