Can I upload an Excel file?

You can upload Excel files (.xlsx) with up to 300,000 rows. For larger datasets, please use our CSV file upload. Workbooks with several sheets are supported: we select the first sheet that contains data, and you can choose a different sheet in the upload wizard. One sheet is processed per upload. The header row is detected automatically and does not have to be the first row; you can change it in the preview. The file must contain at least one column with first names, the country column is optional. The result keeps your original workbook and adds the gender columns. For reasons of data protection, uploaded files will be automatically deleted after one year. Download sample file here. Example:
