How would I go about setting up a scheduled job that runs each night, picks up a CSV file from some arbitrary location and replaces an existing asset in Matrix?
You would probably need to write a custom script to do that, that would sit on the server and be attached to the cron that runs. I don’t believe you would be able to do this in an easy way using functionality in the Admin interface, but it all depends on what asset type and data you are replacing from the CSV file?
It’s an actual CSV file I’ll be updating. I’ve contacted Squiz who have confirmed your suggestion that it will be a script on the server. Thanks.
