I’d like to display a CSV or Excel file from a card’s attachments within an iFrame.
I’ve played around on Glitch for the past 10 hours trying to come up with a custom power-up to display either an Excel file or a CSV file (as an HTML table) as a section within a card. For the life of me, I cannot figure it out. I can get an external file (hosted elsewhere) to show up in the iFrame, but what I’d like to do is display the power-up/section whenever there is an attachment present called “equipmentlist.csv” or the like.
I assume I have to call for a list of the attachments on the current card, then grab the ID from the attachment called “equipmentlist.csv”, but the power-up tutorials are nothing less than confusing.
