I am using this formula.
=COUNTIFS(EXCEL_TAB!$A$1:$A$999999", "*"&"#_CELL_VALUE"&"*").
How can I specify that that for #_CELL_VALUE, this can be any number followed by _CELL_VALUE? The reason is because the data has the values S_CELL_VALUE (the letter S) and #_CELL_VALUE (# is any number). So I need to differentiate them.
Sample Data
RS_CELL_VALUE, 11_CELL_VALUE
RS_CELL_VALUE
11_CELL_VALUE
12_CELL_VALUE
13_CELL_VALUE, RS_CELL_VALUE
Attempt code
=COUNTA(REGEXMATCH(Data!A1:A999999, "*[0-9]_CELL_VALUE*"))
