Spreadsheet function – How to interleave rows of data in Google Sheets or Excel

I have data on several different worksheets and I want to combine them into one sheet. The data is text, not numeric. I can do this work in Google Sheets or Excel.
J & # 39; have:

Sheet1 R1

Sheet1 R2

Sheet2 R1

Sheet2 R2

I want to consolidate this in Worksheet 3:

Sheet1 R1

Sheet2 R1

Sheet1 R2

Sheet2 R2
