What does the error message “Headers not Found” mean?
When you try to add a new Excel spreadsheet data, you may encounter an error message saying, “We couldn’t find any headers in your data.” When you add a new dataset, we need to process (geocode) your locations to find the latitude and longitude coordinates. This allows us to plot your locations correctly on the map. When you paste your spreadsheet data, we need to be able to recognize your dataset. It would help if you can label each column of data from your spreadsheet. Please see our Getting Started with Mapping from Excel Spreadsheet Data to see how you can structure your Excel spreadsheet so we can recognize your address columns.
