Using Conditions for Attachments

I’m trying to build a conditional process that extracts an Excel attachment from the trigger email and converts it to a table. The email that triggers the process will have two attachments- 1 PDF and 1 Excel. Since I don’t know if the order of the attachments will always be attachment1= PDF attachment2= Excel, I figured a condition would work best so I created two conditional steps:

Extract invoice Excel from email if attachment 1 is NOT a PDF (therefore should be Excel)

  • uses {{trigger-attachment}}
  • Condition: If fields["trigger-attachment-filename"] does not end with .pdf


Extract invoice from email if attachment 1 IS a PDF (therefore the Excel file is attachment 2)

  • uses {{trigger-attachment-2}}
  • Condition: If fields["trigger-attachment-filename"] ends with .pdf

But the triggers don’t seem to be working. What am I missing?
Thank you!

    Hey @Anna_272419,

    The best thing to do is use the trigger-attachments table, which contains an Extension column. From there, you can use Tables: Look up data in a column to return the File, which will be in a URL format. You'll need to then use Text: Find text next to other text to extract just the alphanumeric file ID from the URL.

    Once you have the file ID (it will be the --first-match field from the last step), you can use that as your input in the above steps.

    Hi Thomas,
    Thank you for your response! That seems more complicated than it really should be.
    Will the Text: Find text next to other text function work if the file name of the invoice document is different every week?

    Hi @Anna_272419.

    The trigger-attachments table will have the following columns: file | Name | Type | Extension | Size in Bytes | Location

    Only two steps are needed to designate a specific file extension for use in your process. You may wish to add additional conditions if you want to accommodate a scenario where multiple attachments are present with the same extension.

    Tables: Look up data in a column
    In the Extension column, search for xlsx. You can return just the file column, as that is all that is needed. The value here is a URL in this format: https://{teamname}{teamname}/files/{fileid}/download

    Text: Find text next to other text
    In the url, you want to extract the {fileid} between this text: https://{teamname}{teamname}/files/{fileid}/download. Try the following configuration (you need to replace {teamname} with your company's team name):

    after-text: https://{teamname}{teamname}/files/
    before-text: /download

    One output from this step will be {prefix}--first-match. This will be your file {fileid}, which you can then dynamically reference in e.g. Excel: Convert spreadsheet to table. There should be no need to worry about the file name with an approach like this one.
