To refer to a cell, type the column letter followed by the row number. These letters and numbers are called row and column headings. By default, Excel uses the A1 reference style, which refers to columns as letters (A through IV, for a total of 256 columns), and refers to rows as numbers (1 through 65,536).
![]() Excel Column Numbers Serial Number Entered InDeleting or inserting a row won’t affect other record ID’s. The serial number entered in a row will not change once it’s entered. Easy to use and only requires manually entering two values.![]() You can copy and paste the formula down when new rows are added. Easy for someone to understand what the formula is doing. To do this quickly, double click on the fill handle of the cell which contains the formula. In this example B3 is the cell directly above.Now you can copy and paste this formula down the remaining rows. Then in the next row enter the above formula. = B3 + 1Enter the value 1 into the first row of your data. Use the same formula for the entire row. The formula can be applied consistently for each row.The SUM function will count text values as zero, so you can safely reference the column headings when the formula is in the first row without producing a #VALUE! error. = SUM ( Above, 1 )Enter the above formula into the first row and then copy and paste it to the end of your data.Using the SUM function is a small improvement to the previous method as there is no need to enter a value in the first row. The formula is not consistent for the entire column since the first row needs to contain a hard coded value of 1.This method is going to use the same idea where you add 1 to the previous serial number, but it is going use a clever trick to make it more robust.Now when you use the Above name inside a formula it will reference the cell directly above the cell which you are entering the formula. In order to start the serial numbers at 1, we then need to subtract off the row number of the column heading cell. = ROW ( ) - ROW ( $B$2 )Add the above formula, where B2 refers to the column heading cell, into the first row and copy and paste it down.The ROW function returns the row number of the current row when no argument is passed to it. They can slow down your Excel workbook because they are recalculated more frequently.There is an Excel function that can return the current row number and it’s perfect for creating serial numbers. The named range uses the INDIRECT function which is a volatile Excel function. The formula might not be as obvious to someone else looking at your spreadsheet, In this formula C3 is a cell in the first row but another column which will not contain any blank values.Notice the range reference in the formula contains a partial absolute reference with the $ symbol. = COUNTA ( $C$3:C3 )Enter the above formula into the first row and then copy and paste it to the end of your data. The formula needs to reference the column heading cell with an absolute reference.This is another formula option that will rely on counting previous rows of data.In order to use this formula, you will need a column that will never contain blank values as the COUNTA function does not count empty cells. Inserting or deleting a row won’t cause any errors and serial numbers will update accordingly. Neatdesk for mac reviewIn this example C3:C8 is the entire range of a column. Perfect for serial numbers! = SEQUENCE ( COUNTA ( C3:C8 ) )Add the above formula into the first row of data. You need to refer to another column which can’t have any blank values.The SUBTOTAL function is interesting because it can return values based on what cells are visible.It can do a lot more, but this function can also generate a single column of increasing numbers that start at 1. You can insert or delete rows without errors. Easy to implement where the only tricky part is adding the partial absolute reference. Inserting or deleting any row other than the first one won’t produce any errors and your serial numbers will adjust accordingly. No need to copy and paste a formula down to the end of your data set. You only need one formula. Unfortunately, this method would mean you need to manually adjust the count each time you add or remove rows of data. = SEQUENCE ( 6 )Another approach is to hard code the row count inside your SEQUENCE function like the above formula. Choose From Data Model from the options. This results in column that can be used as a serial number.To use this calculated column inside a pivot table. = RANK.EQ( Data, Data, ASC )This will open the power pivot add-in and you’ll be able to add the above formula into the table.In this example, the table has been named Data and we are ranking the Email column which contains unique text values. The COUNTA function will require non blank values.This one is a bit weird since it will create serial numbers inside a pivot table.But it may be just what you’re lookin for.You can use power pivot with a calculated column to number your pivot table rows.Select your table of data and go to the Power Pivot tab and click on Add to Data Model. If you add rows at the bottom of your data set, you will need to adjust the range reference in the SEQUENCE function to include these. ![]()
