Roman Numerals to Number
Parse legacy Roman strings
Feed museum captions, Super Bowl labels, or spreadsheet exports mixing XL and LX into plain integers for sorting and pivot tables. Malformed strings—illegal repeats, modern lowercase mixes—should error or warn depending on implementation; always eyeball edge outputs.
When to use it
Archival metadata cleanup, student worksheet checks, or double-checking clock tower photography captions. To emit Roman from Arabic, use Number to Roman Numerals.
