Malvern Panalytical's flagship software, , is arguably the most powerful tool for XRD data analysis. What many users don't realize is that HighScore Plus can be configured to directly read and import data from Excel files and then save it in its native XRDML format.
Standard Excel-to-XML converters often fail because they lack the specific schema required for diffraction data. The following specialized tools are recommended for maintaining data integrity:
# Date date_elem = ET.SubElement(measurement, 'date') date_elem.text = datetime.now().strftime('%Y-%m-%dT%H:%M:%S')
Converting Excel files to XRDML poses several challenges: convert excel to xrdml high quality
For researchers without a budget, Python offers free, high-quality conversion. This requires scripting but yields perfect results.
Excel is a spreadsheet tool; it stores data in rows and columns but lacks the specific hierarchy required for scientific instrumentation. An XRDML file is structured—it tells the software:
Once this configuration is saved, HighScore Plus will treat Excel files (provided they are properly formatted with, for example, columns of 2θ and Intensity) as importable data sources. You can open the .xlsx file directly, inspect the data, and then save or export the project as a new, fully-formed .xrdml file. This method is the gold standard for high-quality conversion, as the software automatically handles the complex XML schema and populates the metadata fields appropriately. This method was a pivotal solution for researcher Imdadul Islam, who initially struggled with errors when using other converters before successfully implementing these settings in HighScore Plus.

Ensure your Excel columns contain absolute numbers only. Remove text annotations, headers, or units ( ° , cps ) from the data rows.
Parameters: - excel_path: path to Excel file - sheet_name: sheet name or index (default 0) - two_theta_col: column name for 2θ values - intensity_col: column name for intensity values - output_path: output .xrdml path (default: same name with .xrdml) - xray_wavelength: Cu Kα wavelength in Å (default 1.5406) - step_size: step size in degrees (auto-calculated if None) """
| 2Theta | Intensity | |--------|-----------| | 10.0 | 125 | | 10.02 | 130 | | 10.04 | 128 | | ... | ... | An XRDML file is structured—it tells the software:
You cannot skip this. You will need to input this during conversion.
# Save if output_path is None: output_path = excel_path.replace('.xlsx', '.xrdml').replace('.xls', '.xrdml')
Converting an Excel file to the format (an XML-based format used primarily by Malvern PANalytical instruments) is a specialized process. Because XRDML contains specific metadata about instrument configuration and experimental parameters that a flat Excel spreadsheet lacks, you cannot simply "save as" XRDML.
To maintain "high quality" when converting, follow these best practices:
