What is the DOI Cleaner?
Extract and normalize a DOI from DOI URLs, prefixes or copied citation text. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.
Formula or method
Removes common https://doi.org/ and doi: prefixes and surrounding punctuation.
How to use this tool
Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. https://doi.org/10.1000/xyz123 becomes 10.1000/xyz123.
Interpretation and limitations
The tool normalizes the string but does not verify that the DOI resolves or exists. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
