Getting the error “The maximum number of cell styles was exceeded” while operating on Dataset in Excel is a problem that Dataset formatted data has when saving the file as a flat file. Since the file size is large, the format it saves may not support it.
For this solution, it is more convenient to save Datasets with large rows in excel format. For this, an excel file is created using the Excel>Create component. Then the Dataset is transferred to the excel file with the Excel>Write Dataset to Excel component. Then the file is closed with Excel >Save and Close component.
