To get a random value from a table or list in Excel, you can use the INDEX function with help from the RANDBETWEEN and ROWS functions.
In the example shown, the formula in G7 is:
=INDEX(data,RANDBETWEEN(1,ROWS(data...

If you need to count the number of rows in a range, use the ROWS function. In the generic form of the formula (above) rng represents a range of cells.
In the example, the active cell contains this formula:
=ROWS(B4:...

To get the address of the first cell in a named range, you can use the ADDRESS function together with ROW and COLUMN functions.
In the example shown, the formula in G6 is:
=ADDRESS(ROW(data)+ROWS(data)-1,COLUMN(data...

To create a dynamic date list, you can use a formula that increments a start date to create and display additional dates. In the example shown, the formula in B5 is:
=start+ROWS($B$5:B5)-1-offset
where "start" is the...

To extract multiple matches to separate cells, in separate rows, you can use an array formula based on INDEX and SMALL. In the example shown, the formula in E5 is:
{=IFERROR(INDEX(names,SMALL(IF(groups=E$4,ROW(names)-...

You can get the first column (i.e. the starting column number) in a range with a formula based on the COLUMN function.
In the example shown, the formula in cell F5 is:
=MIN(COLUMN(data))
where data is a named range...

If you need to count the total number of cells in a rectangular range, you can do so with the ROWS and COLUMNS functions. In the generic form of the formula (above) rng represents a range of cells.
In the example, the...

To calculate the average for the last N values n an Excel table (i.e. last 3 rows, last 5 rows, etc.) you can use the AVERAGE function together with the INDEX and ROWS functions. In the example shown, the formula in F5...

To retrieve and display values sorted with a helper column, you can use an INDEX and MATCH formula, with a little help from the ROWS function. In the example shown, the formula in F5 is:
=INDEX(sales,MATCH(ROWS($D$5:$...

To flag the last n rows in a range, you can use helper column with a formula based on the ROW and ROWS functions. In the example shown, the formula in cell E5, copied down, is:
=ROW()-ROW(INDEX(data,1,1))+1>ROWS(...

To get the last row number in a range, you can use a formula based on the ROW, ROWS, and MIN functions. In the example shown, the formula in cell F5 is:
=MIN(ROW(data))+ROWS(data)-1
where "data" is the named range B5...

To get the full address of a named range with an Excel formula, you can use the ADDRESS function together with the ROW and COLUMN functions. In the example shown, the formula in G5 is:
=ADDRESS(ROW(data),COLUMN(data),...

To count rows in an Excel table, you can use the ROWS function. In the example shown, the formula in I4 is:
=ROWS(Table1)
Note: with just the table name, ROWS will count data rows only.
