Spreadsheet/database for collection

Does anybody here use a spreadsheet or database to document their collection?

 

There used to be a nice app called Itemizer that you could use to catalog anything. Add a pic and such. I don't know if it's been updated or not.

 

I use a simple Excel sheet to keep an inventory. I keep these data of each prop I buy:

• Movie / Series / Franchise
• Prop
• Original Creator of the Replica
• Date of purchase
• Price
• Price in Euro
• Paid through (PayPal, Money Transfert, traded for X)
• Place of Purchase (The RPF, COW, eBay, Webshop, etc...)
• Bought from (Nickname on forum or eBay
• Full name of seller
• E-mail of seller

I also have a color code: props I'm willing to sell are in blue. Once sold, I strikethrough the line, but keep it in the excel as reference.
I also have a "status" colum in front of each so I can see which props are ordered / paid for / delivered, etc...
