Why does Sumif not work sometimes?
SUMIF Not Working Because of Uneven Data Format
Having numbers formatted as text is possibly well defined otherwise the numbers are not so easy to handle. Here you will see that the sum range has text values rather than numbers. As you know that text values can never be summed up, so the result we get will be 0.
Problem: The criteria string is more than 255 characters
The SUMIF/SUMIFS functions returns incorrect results when you try to match strings longer than 255 characters.
SUMIFS has two limitations. It doesn't work on closed workbooks. This also applies to the other conditional functions mentioned at the start of the article. If you are using external file ranges, the files must be open for the SUMIFS to return a result.
You can enter up to 127 range/criteria pairs.
The most common reason for an Excel formula not calculating is that you have inadvertently activated the Show Formulas mode in a worksheet. To get the formula to display the calculated result, just turn off the Show Formulas mode by doing one of the following: Pressing the Ctrl + ` shortcut, or.
The most common reason for AutoSum not working in Excel is numbers formatted as text. At first sight, those values may look like normal numbers, but Excel regards them as text strings and does not include in calculations.
The only difference between Excel SUMIFS & SUMIF functions is that SUMIFs can check for multiple criteria at once, while SUMIF can check for one criterion at a time. The SUMIF formula returns the sum of cells based on one criterion (a result that matches one condition).
This function is very similar to SUMIFS, but it is more mathematical calculation-based while SUMIFS is more logic-based. You can use SUMPRODUCT to find the sum of products as well as conditional sums. SUMIFS cannot be used to find the sum of products. For our example, we have added one more column to the table.
SUMIFS in excel returns 0 when it does not find the value.
The reason SUMPRODUCT will not work is it tries to multiply a string, albeit an empty string but a string none the less, with numbers, which will throw an error. The array formula ignores all the empty string cells and skips them.
