Import sticky notes from Spreadsheet doesn't work

@SarahmeetMiro - While .csv files will open in a spreadsheet application, e.g., MS Excel, they do not contain the same formatting data that Miro is expecting to see when copied to a clipboard. Instead, CSV is basically plaintext data with commas in between the values. 

Try opening the CVS file in your spreadsheet application, saving it (Save as...) that application's standard format, e.g., MS Excel's .xlsx, and then copying-pasting into Miro.
