Frequently Asked Questions about Roman Numerals Conversion
What range converts?
The classical system has no zero and no agreed symbols above 3,999 without overlines, so expect faithful output inside the common range.
Is the reverse direction strict?
It accepts standard forms; non-classical spellings like XIIII should be corrected to XIV before relying on the result.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Roman numeral text.
What should I check before using the result?
Open the Roman numeral text in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
