Have you ever wondered how to lookup and retrieve the column header in Google Sheets? Let’s dive in and explore this useful feature that can save you time and effort in organizing your data.
The Query Formula: A Powerful Tool
Imagine you have a table with multiple columns in Google Sheets, and you want to search for a specific value in the first column. But you not only want to find that value, but you also want to retrieve the corresponding column header based on a condition.
For example, let’s say you have a list of names in column A and a row of dates as column headers. You want to search for the name “Julia” and return the dates where she was absent (indicated by “A” in the corresponding column).
The formula you can use to achieve this is:
=query(transpose(query(A2:F6,"Select * where A='Julia'",1)),"Select Col1 where Col2='A'")This formula will return the dates 3/1/18 and 5/1/18, as Julia was absent on those days.
How Does the Query Formula Work?
Let’s break down how this formula works. The inner Query function retrieves the header row and the row that contains the name “Julia” in column A. This gives us two rows of data – the first row with the headers (dates) and the second row with the status “P” (Present) and “A” (Absent).
To make these two-row outputs into two columns, we use the Transpose function. The first column contains the headers, and the second column has the values “P” and “A”.
Finally, the outer Query function returns column 1 if column 2 matches “A”, effectively giving us the desired column header(s).
This formula is a powerful way to lookup and retrieve the column header in Google Sheets, with the added benefit of conditionally returning the header based on a specific criteria.
Adjusting the Formula for Different Data Ranges
What if your data range is different? Don’t worry, you can easily adjust the formula accordingly.
For example, if you have an unlimited number of rows, you can modify the formula as follows:
=iferror(query(transpose(query(A2:F,"Select * where A='Julia'",1)),"Select Col1 where Col2='A'"))By removing the row limit (e.g., changing A2:F6 to A2:F), the formula can support any number of rows. Additionally, we encapsulate the formula within the IFERROR function to return a blank result instead of an error if the search key is not found.
Similarly, if you have a different number of columns, you can adjust the reference A2:F to A2:Z or any other relevant range.
One More Example: Lookup and Conditionally Retrieve the Column Header
To illustrate the versatility of the formula further, let’s consider another example.
Suppose you have a table showing class-wise dress color codes on weekdays in a school. You want to find the classes with the dress color code “Blue” on Wednesday.
The formula you can use is:
=iferror(query(transpose(query(A1:K,"Select * where A='Wednesday'",1)),"Select Col1 where Col2='Blue'"))Just like the previous example, this formula retrieves the column header(s) based on the condition specified, in this case, finding classes with the dress color code “Blue” on Wednesday.
Conclusion
Google Sheets’ Query formula is a powerful tool for looking up and retrieving column headers based on specific conditions. Whether you need to find absent students or match certain criteria, this formula can streamline your data analysis and save you valuable time.
