You can remove leading, trailing, and extra spaces between characters and numbers in Excel using TRIM(), SUBSTITUTE() or Find and Replace.

Then use the SUBSTITUTE () function to replace the non-breaking space with normal space. And then use the TRIM () function to remove all spaces from both ends of the original text string.

Excel's Trim function will remove all but one space between words; however, it cannot remove non-breaking spaces – this requires a combination Excel's Substitute and Trim functions.

Determine the "starting_position" -- the character position at which the trailing spaces begin -- by using the TRIM function to measure the length of the text in cell A1 without the trailing spaces.
