majorDimension property

The major dimension of the values.

For output, if the spreadsheet data is: A1=1,B1=2,A2=3,B2=4, then requesting range=A1:B2,majorDimension=ROWS will return [[1,2],[3,4]], whereas requesting range=A1:B2,majorDimension=COLUMNS will return [[1,3],[2,4]]. For input, with range=A1:B2,majorDimension=ROWS then [[1,2],[3,4]] will set A1=1,B1=2,A2=3,B2=4. With range=A1:B2,majorDimension=COLUMNS then [[1,2],[3,4]] will set A1=1,B1=3,A2=2,B2=4. When writing, if this field is not set, it defaults to ROWS. Possible string values are:

• "DIMENSION_UNSPECIFIED" : The default value, do not use.
• "ROWS" : Operates on the rows of a sheet.
• "COLUMNS" : Operates on the columns of a sheet.
