Below are some guides for exporting orders as CSV, also known as Comma-Separated Values. It’s probably the most common way to export and import data in the world, so this will satisfy most people.
Below is a screenshot of the export screen.
See the Google Sheet example below of the CSV export. You can also click here to download an example CSV file.
NOTE: I added the header column coloring in the spreadsheet to make it easier to read. CSV does not have any formatting on it, so you’ll need to add it yourself.
