Excel’s ROMAN Function: How to Convert Numbers into Roman Numerals
The ROMAN function in Excel is a built-in function that allows you to convert regular numbers into Roman numerals. To use the ROMAN function, simply enter “=ROMAN(number,[style])” into a cell, where “number” is the value you want to convert and “style” is an optional argument that specifies how the output should be formatted.
For example, if you wanted to convert the number 125 to Roman numerals, you would enter =ROMAN(125) into a cell, which would return “CXXV”.
Mastering Excel’s ROMAN Function: Syntax, Arguments, and Limitations
The syntax for the ROMAN function is relatively straightforward, with two required arguments: the number you want to convert to Roman numerals, and an optional argument that controls the formatting of the output.
One important limitation to keep in mind when using the ROMAN function is that it can only convert numbers between 1 and 3999. If you try to convert a number outside this range, Excel will return an error message.
For example, =ROMAN(4000) would return an error message.

By default, Excel’s ROMAN function converts numbers to uppercase Roman numerals. However, you can also format the output as lowercase letters by including a second argument of 0 in the function.
For example, if you wanted to convert the number 225 to lowercase Roman numerals, you would enter =ROMAN(225,0) into a cell, which would return “cxxv”.
Breaking the Code: Using Excel’s ROMAN Function to Convert Negative Numbers
Excel’s ROMAN function can also be used to convert negative numbers to Roman numerals. The resulting value will be enclosed in parentheses to indicate that it is negative.
For example, if you wanted to convert the number -666 to Roman numerals, you would enter =ROMAN(-666) into a cell, which would return “(DCLXVI)”.
Decimal Dilemmas: Tips for Rounding and Truncating Before Using the ROMAN Function
The ROMAN function in Excel can only convert whole numbers, so if you need to convert a decimal number to Roman numerals, you will need to round or truncate it first.

Out of Range? What to Do When Your Number is Too Big (or Small) for the ROMAN Function
If you need to convert a number that is too big or small for the ROMAN function, you may still be able to achieve the desired result by breaking the number down into smaller parts and converting each part separately.
For example, if you wanted to convert the number 4000 to Roman numerals, you could break it down into 3000 + 1000 and then use the ROMAN function to convert each part separately before concatenating them together.
Excel Functions 101: Using the ROMAN Function in Combination with Other Built-In Functions
The ROMAN function in Excel can be combined with other built-in functions to perform various calculations and manipulations involving Roman numerals.
For example, you could use the CONCATENATE function together with the ROMAN function to concatenate multiple Roman numerals together, or use the LEFT and RIGHT functions to extract specific digits from a Roman numeral.
Transforming Strings with Non-Numeric Characters into Roman Numerals Using Excel
Excel’s ROMAN function can also be used to convert strings that contain non-numeric characters into Roman numerals by using the SUBSTITUTE function to remove the unwanted characters first.
For example, if you wanted to convert the string “MCMXCIV” (which represents the year 1994) to Roman numerals, you could use the formula =ROMAN(SUBSTITUTE(“MCMXCIV”,”I”,””),0).
Customizing Roman Numeral Symbols in Excel: Options and Limitations
