How to map latitude / longitude data grid on the map of Europe?

I am preparing a presentation. Data collection I have a lat / long Excel chart. (As assigned on a grid equidistant) need to match worksheet with a map of Europe. What kind of card I use? (Mercator, etc.).

I am a Navy captain and has been at sea all my life to deal with maps and compasses so here's the solution to your response, it is necessary "Mercator", which is also known in terms of navigation as "Mercator Chart" because the Lat Long and straight lines intersect at 90 degrees (right angle), while the "road gnomonic" or "gnomonic chart is a map such as land and Lat Real Long poles are combined and expanded, coming to Ecuador. Excel is obviously reflecting the Mercator test box and if you have any questions, please email me and I will answer all your questions as soon as possible.
