Example CSV File (in this case generated in Google Sheets)*...
* CSV Guidelines...
CSV files are spreadsheets generated in any popular tabulation program and published to CSV. They should have the following column headers: Name; Address; Latitude; Longitude; Notes; Group; Use HTML; Button Link; and Tags. Name, Notes, Group and Tags may be blank, but either Address or Latitude and Longitude must contain values for pins to be placed. Name identifies PINs, and Notes add respective write-ups (limited to 130 characters, plus/minus 20). Group is akin to category and determines how PINs are bundled. Use HTML should say "true" or "false" and, if "true", include a URL as last line in Notes. Button Link must contain a URL to function. Tags must be comma separated.
