AC Question

Hi,

I am not sure if this is the correct place to put a question like this but I urgently need an app to manage my work. I use many excel sheets for my work with thousands of entries in them. They have 2 - 3 columns; serial number, name, quantity. I want a app which can show me quantity of any class when a name or serial number is entered. Please suggest any such app.
