Use 'Save and Add another'
On card edit mode, there is a link called 'Save and add another'. Clicking this link will save the current card and directly take user to new card. This feature helps user to create new card sequentially without getting out of card edit mode.

Use Special Headers
You can create special headers using wiki page. Clicking this link will take user to new card's edit mode page.

Use 'Import from Excel'
Click on 'Import from Excel'.

Copy data from excel and paste them into provided text area.

If you intent to create new cards, you don't have to provide the 'Number' column. Mingle will automatically assign card numbers to each imported card. Specifying card number can cause to update existing card instead of creating new card.
Click 'Next to preview' and follow the process to complete the import. Learn more rules about Import from Excel.
