A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
To use the sheet names that are in Column A to retrieve data from A22 in those sheets, use this formula that I show in B1 and filled down.
=INDIRECT("'"&A1&"'!A22")
NOTE: In this instance because the cell number is included as text in the concatenate structure the A22 reference will not change as the formula is filled down. If it needs to change there are other ways to express that cell reference that can make that adjustment, but it doesn't seem that is the objective here.
