Somewhere in this workbook is a sheet called A. A! refers to the sheet
titled 'A'

All of these are absolute references within that sheet.

Absolute references, denoted by placing the $ before the column or row are
references that do not update as the formula is moved. $A1 when moved will
update only the row portion (the 1 will become 2, 3, 4, etc). A$1 will only
update the column portion (A1, B1, C1, etc). $A$1 will not update row or
column when moved.

The : between two reference points indicates a range that includes all cells
that would be included if you clicked and dragged your mouse between those
two points on the spreadsheet.

I received a spreadsheet that includes a list of formaulas that I do not
understand. The person that sent it, did not create it and was unaware the
codes existed. What do these cell do and what are they referencing?
=A!$B$1:$I$6
=A!$C$25
=A!$A$1:$M$55
=A!$C$23
=A!$E$23
