How to use the ARABIC Function in Excel?

To understand the uses of this function, let’s consider a few examples:


Example 1

If we provide the string as IV, the ARABIC function will return the value 4. The formula to be used is =ARABIC(“IV”).

Similarly, below are a few more examples:


ARABIC Function


Example 2

We can also provide a reference to the cell containing the string. For example, as shown below, we provided a cell reference:


ARABIC Function


As seen above:

  • An empty string returns 0.
  • The space before and after the string is ignored.
  • When giving a cell reference, we do not need to use quotation marks.


Things to remember about the ARABIC Function 

  1. #VALUE! error – Occurs when the given value is an invalid value. So, this error will occur when the numbers, dates, and text are not valid Roman numerals.
  2. #NAME? error – Occurs when we provide the string without “”.
  3. When we use an empty string as an input value in this function, that is (“”), then Excel returns 0 for it.
  4. The function accepts 255 characters, which is the maximum length of the argument. So, the largest number that can be returned is 255,000.
  5. It is indifferent to the case of the text. So, a text entered in UPPER case of the text argument will give the same result as the text entered in lowercase. For example, MXMV will return the same result as mxmv – 1995.
  6. The function ignores leading and trailing spaces. For example, =ARABIC(” MXMV”) will give same result as =ARABIC(“MXMV”).
  7. It supports the evaluation of a negative Roman numeral, even though a negative Roman number is non-standard. For this, we need to insert a negative sign before the Roman text. For example, =ARABIC(“-MXMV”) = -1995.
  8. The ARABIC function is opposite of the ROMAN Function.
