Fiil was born in Hvidsten on 12 June 1920 to house proprietor and bicycle dealer Marius Fiil and wife Gudrun Fiil.
He was confirmed in Spentrup church in 1934 on the first Sunday after Easter, while living in Hvidsten with his family. He received his confirmation with a waiver, since he had not yet turned 14. During the occupation the family and other locals formed a resistance group, the Hvidsten group.
The group helped the British Special Operations Executive parachute weapons and supplies into Denmark for distribution to the resistance.
The following month De frie Danske reported that several arrestees from Hvidsten had been transferred from Randers to Vestre Fængsel. On 2 July 1945 the remains and Fiil and his father were found in Ryvangen and transferred to the Department of Forensic Medicine of the university of Copenhagen.
The following day an inquest in the Department of Forensic Medicine of the university of Copenhagen showed that Fiil was executed with gunshot wounds to the chest. On 10 July he was together with the seven other executed group members cremated at Bispebjerg Cemetery.
In the 2012 Danish drama film Hvidsten Gruppen (This Life) Niels Fiil is portrayed by Thomas Ernst.
In addition to being a member of the Hvidsten group, Fiil was also a farmer while helping out at the inn. Six months later the January 1945 issue of the resistance newspaper Frit Danmark (Free Denmark) reported that on 29 June the previous year Fiil and seven other named members of the Hvidsten group had been executed. The remains of the six other executed members of the group were found in the same area three days later.
In 1945 a memorial stone over the eight executed members of the Hvidsten group was raised near Hvidsten kro.
Similarly a larger memorial stone for resistance members including the eight executed members of the Hvidsten group has been laid down in Ryvangen Memorial Park.
