I recently made the post here, in which I presented a solution to the problem of returning a value based upon matching a single criterion in a given column across multiple worksheets.
In this follow-up post I will look at the analogous case in which we are not matching a single criterion, but several. As mentioned in the first instalment, I will look at two solutions to this problem, one in which we make use of an extra “helper” column in each of the relevant worksheets, and one in which we do without such aids.
Most people with an average level of ability in Excel are perfectly capable of using VLOOKUP when this operation is performed over a range within a single worksheet.
But what happens when we wish to extend our search to multiple worksheets, and so return the first match from whichever sheet happens to be the first which contains our search value(s)?
In this post I will present a solution for such cases in which we have a single criterion to be matched in a given column across multiple worksheets.
In the next instalment (to follow shortly) I will also look at cases in which we are not matching a single criterion, but several. In this situation by far the simplest method is to use an extra “helper” column in each of the relevant worksheets in which we first perform a concatenation of the fields of interest. By doing this we ensure that it is a relatively straightforward case of extending the solution designed for one criterion to work also with multiple criteria.
In this post I would like to clear up what appears to me to be a rather widespread misunderstanding of how COUNTIFS/SUMIFS operate, in particular when we pass arrays consisting of more than one element as the Criteria to one or even two of the Criteria_Ranges.
This latter technique is used when the criteria in question are to be considered as “OR” criteria, which is not to be confused with cases where we wish the criteria passed to be calculated rather as “AND” critieria.
For example, given the following data:
