XLSX in sintesi
XLSX
XLSX emerged with the Office Open XML shift away from older binary spreadsheet files and became a common denominator for modern spreadsheet interchange.

FLAC
FLAC grew inside the Xiph open-media ecosystem and later gained a formal RFC description, which strengthened its standing as a stable open lossless format rather than a niche hobbyist codec.
