Enter a word or phrase in the first field.
As you enter text, matches are highlighted. The first match is selected and highlighted in yellow.
Enter the replacement word or phrase in the second field.
Important: If you leave the second field blank, all instances of the text are deleted when you replace the found text.
Review and change the text matches:
Move to the previous or next match without making a change: Tap the arrows.
Replace the selected match: Tap Replace.
Replace all text matches with the replacement text: Touch and hold Replace, then tap Replace All.
Replacing a table value updates both the displayed value and the underlying value. For example, if you replace “1/2” with “1/3,” the underlying value changes from “0.5” to “0.333333.”
You can’t replace matching text in cells that contain a formula.
