EasySpreadsheet has an advanced, built-in spelling checker.
To check the spelling of your sheet:
Go to the Tools menu, and click Spelling checker. Or, in Advanced Mode, click the Check Spelling icon (with a red checkmark).
A message box will pop up, asking you if you want to continue checking. Click OK.
If there are misspelled words (or, words not in your dictionary), a Check Spelling window will appear.
If the word is not actually a spelling mistake (for example, perhaps it is a name), then click the Add button. The word will be added to your dictionary.
If the word is not actually a spelling mistake but you do not want to add the word to your dictionary, then click the Ignore button.
If the word is a spelling mistake, you should change it.
If have made the same spelling error more than once in your sheet, you can correct all of the occurrences simultaneously. Click the Change All button
At the bottom left of the Check Spelling window is an Options button. If you click the Options button, you will be given choices on how you want the spelling check routine to work. For example, you can have it ignore capitalized words. (See Spelling Options.)
You can cancel the spelling check at any time. Simply click the Cancel button.
When the spelling check is complete, a window will appear to let you know. It will tell you how many errors were detected, and how many of these were changed. Click OK, and you will be brought back to your sheet.
