This post will guide you how to count number of occurrences in whole workbook in Excel 2013/2016 or Excel office 365. How do I count how many times a string is repeated in all worksheets in Excel. You may be want to count occurrences for the number of times a certain value matches across all worksheets in your current workbook. And you can do this by a formula based on the SUMPRODUCT  function, the COUNTIF function and the INDIRECT function in Excel.

General Formula:

The below general formula can help you to count occurrences in a certain range across the entire workbook in Excel. Like this:

=SUMPRODUCT(COUNTIF(INDIRECT(“‘”&mysheets&”‘!”&range),criteria))

Note: you need to put the names of your all worksheets(sheet1,sheet2,sheet3) into cells. And then select this range, clicking on the drop-down arrow along the formula bar and name this range as “mysheets”.

Count Occurrences in Entire Workbook

Assuming that you have a data of list in your workbook, and this workbook has three worksheets. And those three worksheets are “Sheet1”,”Sheet2” and “Sheet3”that contain name lists in range B2:B6. And you want to count the number of occurrences of the product name “excel” within a specified range B2;B6 across those three worksheets. And you can use a formula based on the SUMPRODUCT function, the COUNTIF function and the INDIRECT function. Like this:

=SUMPRODUCT(COUNTIF(INDIRECT(“‘”&mysheet&”‘!B2:B6”),C1))

Let’s See That How This Formula Works:

=”‘”&mysheet&”‘!B2:B6″

You know that mysheet is a named range that contains “sheet1”,”sheet2” and “sheet3”. This formula will return an array result like this:

{“‘sheet1’!B2:B6″;”‘sheet2’!B2:B6″;”‘sheet3’!B2:B6”}

=INDIRECT(“‘”&mysheet&”‘!B2:B6”)

The INDIRECT function can be used to convert each text value to a cell reference.

=COUNTIF(INDIRECT(“‘”&mysheet&”‘!B2:B6”),C1)

The COUNTIF function can be used to count the number of occurrences the value(cell c1) in those range B2:B6 match the value “excel”. And it also returns an array result contains count values from each worksheet.

{2;2;2}

Finally, the SUMPRODUCT function sums the above array results returned by the COUNTIF function.
