Looking For A National Budget Dataset

Hi everybody, I am writing a paper about the effects of politics on military spending and found a website with an amazing excel spreadsheet that had each country and data from the 1940s to present. It had various tabs with GDP, national budget, military spending, etc. I used it for my data sets in STATA, but found it on a library computer and forgot to save the link or write down the website and now am looking everywhere for it to cite in my bibliography and cannot find it. If anyone knows what spreadsheet I’m talking about or could help me find it I would be extremely grateful!
