Question: How would you manage multiple people adding same kind of data into a spreadsheet? Situation: This company uses Excel spreadsheet as final form for their sales peoples. So, each person pulls his/her own data from CRM subsystem, and adds to this spreadsheet. Well, a moron overwrote other people's entries, and lost entire weekend's work. So they ask me, and I said, "I don't know, but I'll ask around". In my previous companies, such spreadsheet would be on a server. And, whenever someone opens to edit, it would lock the file. But, this only addresses "access". Not the "content". Possible Solution: I'm thinking "template". Each person would be populating same kind of data into spreadsheet. So, maybe a script merges data from his/her template? Maybe, a "web form"? I don't know.
