It is known that Excel sheets can display a maximum of 1 million rows. Is there any row limit for csv data, i.e. does Excel allow more than 1 million rows in csv format?
CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines.
Excel will actually ask you whether you want to proceed when importing more than 1 million data rows. It suggests to import the remaining data by using the text import wizard again - you will need to set the appropriate line offset.
