Need help from experts : Searching for History Database (Excel or CSV)

Jul 2019
Quebec, Canada
Hi, the title say all... i'm french and i need a very detailed software or database of all events. Something like Wikipedia, but more like a timeline... that could be opened with Access, Excel or in CSV.
I also search for a database of all leaders or political rulers of all times.

Did anybody know someone or some available resources that can be downloaded for free. Thanks.
