pub fn parse_excel_date_text(input: &str) -> Option<NaiveDate>Expand description
Parse date text using Formualizer’s deterministic en-US spreadsheet convention.
Numeric slash dates use month/day/year ordering. Two-digit years in slash
and English month-name forms use Excel’s fixed window: 00..=29 means
2000 through 2029 and 30..=99 means 1930 through 1999. ISO dates require
a four-digit year. Parsing has no locale parameter and never consults the
host locale.
