How to use the SUMPRODUCT function in Excel

The SUMPRODUCT function is not limited to product summing, but can also be used for conditional summing, weighted average, etc. 1. The basic usage is to multiply the corresponding elements of multiple arrays and sum, such as calculating the total sales volume and unit price; 2. The conditional summing can be achieved through logical judgment, such as filtering the sales of "East" or "Apple" products, and using the TRUE=1 and FALSE=0 characteristics to combine the array operation; 3. The weighted average value can be calculated, such as multiplying the score and weight and dividing it by the weight sum; 4. When using it, pay attention to the consistency of the scope size, avoiding the entire column reference, treating the text as zero, and using double-negative signs to convert the logical value.
