Part 2/7:
The DSUM function is one of the most prominent database functions available in Excel, designed to sum values based on specified criteria. Its syntax is straightforward: it requires the database range, the field to sum, and the filter criteria.
For instance, consider a dataset of invoices structured into an Excel table labeled "data table." If one needs to sum amounts specifically from all level one invoices, the user would specify the type column and list "level one” as the criterion. The DSUM function would then aggregate the values, providing a quick sum – a significant time saver compared to using multiple SUMIF functions.
