I have a Spreadsheet where each tab is a month (January, February, ..., December) and they have exactly the same structure.
In order to combine all the information in a single sheet I used an array:
={January!A5:Q;February!A5:Q;March!A5:Q;April!A5:Q;May!A5:Q;June!A5:Q;July!A5:Q;August!A5:Q;September!A5:Q;October!A5:Q;November!A5:Q;December!A5:Q}
But I wanted to filter the entries of each month based on some conditions, so I used the QUERY function:
=QUERY({January!A5:Q;February!A5:Q;March!A5:Q;April!A5:Q;May!A5:Q;June!A5:Q;July!A5:Q;August!A5:Q;September!A5:Q;October!A5:Q;November!A5:Q;December!A5:Q},"select * where Col3 = 'X'",0)
I get the desired result. The extra plus that I want to achieve is to identify the month at each line belongs, in other words, the sheet were the data is pulled. And I want to see that without adding columns or extra fields on the source sheets.
How do I do that?
