Smartsheet's spellchecker only works on the cell you're editing. To check your whole sheet, you'd have to click through every single cell. I'm going to show you how to spellcheck your entire sheet at once. First, download SSFeatures from ssfeatures.com. Open your sheet in Grid view. SSFeatures automatically scans your entire sheet and underlines misspelled words in red. Click any underlined word and SSFeatures will show you the correct spelling. Click the suggestion to apply it or click ignore to add that word to your custom dictionary. You can completely customize the spell checker. Click the SSFeatures button. Hover over spell check. In this menu, you can change your dictionary to any of 80 supported languages and dialects. You can also manage your ignored words or disable the spellchecker on specific columns, sheets, or entirely. With SSFeatures you can catch every spelling error across your sheet in seconds without clicking through cells one by one. And unlike other spellcheckers, your data never leaves your browser.
