How to Convert Numbers to Roman Numerals in Excel

ROMAN turns numbers into Roman numerals for film credits, chapter headings and festival editions — no lookup table needed.

You will learn to

  • Convert a year to Roman numerals
  • Build a heading that contains a Roman numeral
  • Calculate an edition number and convert it

How it works

ROMAN(number) converts a whole number from 1 to 3999 into classic Roman numerals as text: =ROMAN(2026) returns MMXXVI and =ROMAN(14) returns XIV. Decimals are truncated, 0 returns an empty string, and negative numbers or values above 3999 return #VALUE!.

Because the result is text, you can join it into headings: ="Chapter "&ROMAN(C3). For anniversaries and festivals, calculate the edition number first (year − first year + 1) and then convert it. To go the other way, use ARABIC.

=ROMAN(B2)
