The third section of your export-making process is labeled Export Results. This is where you'll see the list of available exports, their date, the record size, and whether they're scheduled or available for immediate downloading.
You'll notice that the icon for Export Actions changes depending on whether you've scheduled an export, or selected the export to be available immediately:
Natively, Salsa exports a Comma Separated Value file, or .csv. Once you've opened it in Excel or the spreadsheet program of your choice, you can then convert the file to another format if you choose. See your spreadsheet program's instructions on how to get your file saved or exported in the format of your choice.
Congratulations on your export!
