Preparing Your CSV

To convert a spreadsheet into a CSV simply choose “Save As” in your spreadsheet program and choose CSV from the available file types. CSVs cannot contain styling or multiple sheets, so any styling or additional sheets contained in your spreadsheet will be lost when saving. Create a backup of your original spreadsheet prior to exporting to CSV to ensure your data is safe.

Save As .csv from your spreadsheet application

CSV Upload Errors

There are many different programs that can generate CSV’s and as there is no official file standard for CSV, some programs will format them in different ways to others.

If your CSV is formatted as per the instructions above please check the following using a spreadsheet program, such as MS Excel.

  • Double check that your data contains Lat Long coordinates, and that the column names containing the coordinates are name correctly.
  • Open the .csv file in a text editor (not spreadsheet program) and check for trailing commas.

  • Each column in the CSV must have a name. The example below is missing column names. Either delete the column or add a name.

  • There should be no text or spaces before or after the actual data. In the example below, the rows highlighted in red need to be deleted.

  • There should be no carriage returns in your column names. This is indicated by names that break over two lines as shown below. Remove any carriage returns in your column names.

  • Ensure there are no blank columns in the CSV
  • Ensure there are only numbers and no letters in Lat/Lon columns
  • Ensure your columns are separated by commas or semicolons (This will not be apparent in your spreadsheet application, but will be visible by opening your CSV in a text editor).
  • Individual fields cannot contain a comma. If you see a column name with two names and a comma, as per the example below, you will need to edit the fields to separate them into multiple columns.

“My spreadsheet doesn’t contain coordinates. What should I do?”

If your CSV only contains street addresses, you must geocode the addresses into coordinates before uploading to Mango. Please read this tutorial for instructions.

If your CSV does not contain coordinates but has other information such as administrative boundaries, fips codes, zip codes, county or state names, then please read this tutorial for instructions.
