France and Portugal both won on Tuesday to secure qualification for next year's World Cup, but the Netherlands will not be present at Russia 2018 after missing out on the playoffs.
Antoine Griezmann and Olivier Giroud scored the goals as a nervy France defeated Belarus 2-1 in Paris to make sure of top spot in Group A.
Sweden finished second in the table despite losing 2-0 to the Netherlands, which needed to score at least seven goals and win by six to secure a top-two spot.
The Dutch managed to find the net only twice in Amsterdam, both from Arjen Robben in the first half, meaning they will miss a World Cup for the first time since 2002.
Portugal and Switzerland met in Lisbon to decide who would triumph in Group B. Cristiano Ronaldo's European champions ran out 2-0 winners, meaning they finish on top courtesy of their superior goal difference.
Defeat means the Swiss will have to negotiate a two-leg playoff staged in November to qualify, though they will be seeded when the draw is made in Zurich on Oct. 17.
Switzerland will, therefore, avoid coming up against fellow seeds Croatia, Denmark and Italy, with Northern Ireland, Sweden, Republic of Ireland and Greece — which finished second in Group H — the other nations involved.
With Greece winning 4-0 at home to Gilbraltar to move to 19 points, Slovakia is the unfortunate second-place nation to miss out on a playoff berth.
As well as France and Portugal, Belgium, England, Germany, Iceland, Poland, Serbia and Spain all clinched automatic qualification for the tournament by winning their respective groups.
