Please allow us to import/export via a excel spreadsheet, instead of the csv
Thank you for writing in.
We do not plan on adding support for .xlsx formatting as opposed to .csv format because you already have the ability to export from Excel to CSV when you save your spreadsheet.
When you save your file in Excel, choose the file format to be “CSV (MS-DOS) Format”, and you will be able to import to Nimble.
If you have any questions, please feel free to write to email@example.com for support.
