=== W3C tabular data standard ===
In 2013 the [[World Wide Web Consortium|W3C]] "CSV on the Web" working group began to specify technologies providing higher interoperability for web applications using CSV or similar formats.<ref>{{cite web|url=http://www.w3.org/2013/csvw/wiki/Main_Page|title=CSV on the Web Working Group|year=2013|publisher=[[World Wide Web Consortium|W3C]] CSV WG|access-date=2015-04-22}}</ref> The working group completed its work in February 2016 and is officially closed in March 2016 with the release of a set of documents and W3C recommendations<ref>[https://github.com/w3c/csvw CSV on the Web Repository] (on GitHub)</ref>

While the [[well-formed element|well-formedness]] of CSV data can readily checked, testing validity and canonical form is less well developed, relative to more precise data formats, such as [[XML]] and [[SQL]], which offer richer types and rules-based validation.<ref>{{cite web|url=https://www.csvpath.org/topics/validation/schemas-or-rules|title=Rules Or Schemas|year=2024|publisher=CsvPath Project|access-date=2025-02-13}}</ref>
