Excel export threshold Excel exports are intended for relatively small exports, fewer than 500,000 cells, while CSV can handle larger exports. Whenever you export to Excel and the resultant spreadsheet has more than 500,000 cells (by default), the export process stops and you are given the Excel file at that point. In the bottom row, there will be the following message: Export stopped due to excessive size. Use CSV for a complete export: Figure 1.
