See the more common Transitional XLSX/OOXML_2012.įor works acquired for its collections, the list of Library of Congress Recommended Formats Statement for Datasets/Databases, includes XLSX (.xlsx) as a preferred format for datasets.

The markup for the Strict variant is essentially a subset of markup for the Transitional variant, but the schemas use different namespaces and are distributed separately in complete form. The Strict variant of XLSX disallows a variety of elements and attributes that are permitted in the more common Transitional variant ( XLSX/OOXML_2012).
