[3] The Grant family has had a fair bit of success on Catriona Matthew's home track, North Berwick Golf Club.

[10] In 2018, Grant won the qualification for the 2018 Women's British Open at St Annes Old Links Golf Club with a round of 62 (−10), however she missed the cut in the Women's Open at Royal Lytham & St Annes Golf Club after rounds of 78 and 72.

She won her first varsity tournament for the Arizona State Sun Devils at the Dr Donnis Thompson Invitational in Honolulu in March 2020.

She lost in a playoff to Ingrid Lindblad at the 2020 Skaftö Open, but a few weeks later won the Swedish Matchplay Championship, just like Anna Nordqvist, Caroline Hedwall, Maria Hjorth, Helen Alfredsson and Liselotte Neumann before her.

[14] Playing with the Arizona State Sun Devils, Grant won three consecutive individual tournament titles in the spring of 2021.

After a tie for 7th at the season-ending Investec South African Women's Open she captured the Sunshine Ladies Tour's Order of Merit title, ahead of Lee-Anne Pace.

Grant said through a statement via her agent, "with travel restrictions to enter the U.S. still remaining, it is still not an option for me to play LPGA events in the U.S.

In May 2023, travel restrictions to enter the U.S. were released, why Grant started playing LPGA Tour events in the U.S.

In her fourth start on U.S. soil since the release, she captured her first LPGA Tour win in July 2023 at the Dana Open.

[22] In June 2024, Grant won on the Volvo Car Scandinavian Mixed for a second time, after starting the final day 11 shots behind 54-hole leader Sebastian Söderberg, achieving the biggest comeback ever in a golf tournament.
