EZ Fulfil does not support EDI (Electronic Data Interchange) formats, and we don't plan on supporting them in the future.

However, we do support plain text files in CSV format, where you can specify a different character delimiter (tab, comma, semicolon, tilde, pipe, or caret).  You can also specify the file extension (e.g. using .txt instead of .csv).

If the specific EDI format you're looking for resembles a typical CSV file (tabular data), then it might work.

Here are things to note when using our app to mark orders fulfilled and upload tracking numbers in the CSV format:

• we can only fulfill orders in tabular format, where you can include a single header row and the data rows below it
• if the file does not have a header row, you can use the column position number
• you can use different delimiters
• you can filter rows that you don't want read or fulfilled
• you can replace values in your file to ensure the value provided to Shopify is what they expect
• you can add tags and notes with your fulfillment if you have them in your file
• you can mark pending orders paid on fulfillment
• you can schedule the export to run automatically and upload the file to an FTP or SFTP server as frequently as every 15 minutes (you can also do Hourly, Daily, Weekly, or Monthly schedules)
