This is with Google Sheets.

MS Excel is in tabular format consisting of rows and columns.

Explanation:

Row runs horizontally while Column runs vertically. Each row is identified by row number, which runs vertically at the left side of the sheet. Each column is identified by column header, which runs horizontally at the top of the sheet.
