Find and Replace Across a Whole Workbook
Excel's built-in find and replace works one sheet at a time unless you remember to switch it to “Workbook”. This tool counts matches per sheet up front, supports regular expressions with capture groups, and leaves formula cells alone so your calculations don't break.
