"Fifa today provided, as planned, data requested by the attorney general," said a spokesman for the Zurich-based global football body.
Fifa has been in turmoil since last month when 14 current or former officials and sports marketing executives were charged as part of an
investigation by US authorities into alleged corruption.
The fallout led to the resignation of Fifa president Sepp Blatter.
The decision to award the 2018 and 2022 World Cups to Qatar and Russia respectively is also currently the subject of a Swiss investigation.
The BBC claimed that documents were seized from the offices of Blatter, Fifa general secretary Jérôme Valcke and chief financial officer Markus Kattner.
Questioned by AFP, a spokesman for the Swiss public prosecutor confirmed that documents had been handed over but without identifying individuals.
"Fifa has today presented documents and computer data to the public ministry," said a justice spokesman.
In other football-related news, Switzerland defeated neighbour Liechtenstein 3-0 in a friendly game on Wednesday night in Thun.
Blerim Dmezaili opened the scoring for the Swiss side in the 29th minute.
Xherdan Shaqiri added a goal in the 60th minute, eight minutes before Dmezaili scored again, this time on a free kick.
The result leaves Switzerland undefeated in six games.
