A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Assuming the textual date only is in cell A1, format cell B1 as [e.g.,] Short Date, then in cell B1 enter the function:
=DATEVALUE(A10)
Copy down as necessary.
If the cell actually contains "10/23/2022=ISTEXT(B218)" the = & everything that follows it needs to be removed.
If that doesn't provide the desired result please provide a more explicit example of the data as it actually exists in the file.
