I'm back with another fun Card ID question. We are close to the start of our project to re-card all our students, faculty, and staff. This is our first card upgrade since I've worked here (15 years) so the jump from 85% plastic card with bar code / 15% prox cards with bar code to 100% card with prox, mag, and bar code is a huge step. I've done some testing and manually added a mag stripe number to my account in the Card ID field. What I'm trying to find is a way to update the records of the existing users en mass in Pharos. I've read into Userload's ability to update via a text file BUT all I want to update is the Card ID. Ideally, we'd have a file that our card system would export at set times that Pharos could ingest via a Userload scheduled task. My question is can the file be formatted in a way where you don't provide all the fields? I've included an example of what I mean below. In other words, if I have the proper number of commas will it leave those data values alone or will it blank those data values?
