More good news is coming from our development team. Now you can import your clients from CSV files. Supported by Microsoft Excel, the comma-separated values file format is a set of file formats used to store tabular data in which numbers and text are stored in plain textual form that can be read in a text editor. Lines in the text file represent rows of a table, and commas in a line separate fields in the tables row.
At this time we only support import from US/UK CSV format. If you have German, Dutch or Russian locale getting semi-colon as a separator versus a comma, please change your regional settings.
If on Windows machine, go to Windows Start button -> Settings -> Control Panel -> regional settings -> Number Tab (at the bottom).
If on Mac, go to System Preferences->Language & Text->Formats and then change the region to US.
