Would you like a ready-to-use Excel template for high-quality XRDML conversion?
Converting Excel data to the XRDML format is a critical task for researchers needing to import custom or processed X-ray diffraction (XRD) data into specialized analysis suites like PANalytical X'Pert HighScore Plus. Because XRDML is an open, XML-based format, "high quality" conversion requires not just moving raw numbers, but ensuring that metadata—such as wavelength, step size, and instrument settings—is correctly mapped to the XML schema. Top Tools for High-Quality Conversion
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:
PowDLL Converter: Widely considered the "gold standard" for free XRD file interconversion. It can import Excel/ASCII XY files and export them to various formats.
Pros: Supports a massive range of formats (Bruker, Rigaku, Philips, etc.) and is frequently updated.
Download: Available via Software Informer or official developer mirrors.
PANalytical HighScore Plus: If you have access to this software, you can often import Excel files directly by adding .xlsx or .csv as supported extensions in the Automatic Processing settings. Once imported, you can save the file natively as an .xrdml.
XR Delicious (Online): A convenient web-based utility that allows users to upload data in XY format and download it as an XRDML file. It even allows you to modify header information before downloading.
JADE Pattern Converter: A robust tool from ICDD that handles pattern digitizing and conversion across multiple XRD formats. Step-by-Step Conversion Methods Method 1: Using PowDLL (Recommended)
Prepare your Excel File: Ensure your data is in two columns: 2-Theta (X-axis) and Intensity (Y-axis). Save this as a .csv or .txt (Tab-delimited) for the best compatibility.
Open PowDLL: Select your input file and set the "Input Format" to ASCII XY or Excel (if supported by your version).
Configure Parameters: Enter critical metadata like the Wavelength (e.g., 1.5406 Å for Cu K-alpha).
Convert: Set the output format to Panalytical XRDML and click Convert. Method 2: Python Scripting (For Batch Processing)
For high-volume work, you can use Python's pandas and xml.etree.ElementTree libraries to map Excel rows to the XRDML schema. Use pandas.read_excel() to load your data.
Iterate through rows to create the

XRDML files are more than just lists of numbers; they are "transparent and open" documents that contain all information required to reproduce a measurement. A low-quality conversion that omits the Anode Material, Step Size, or Scan Mode may cause errors when performing phase identification or Rietveld refinement in professional software.
Abstract
Microsoft Excel is a widely used spreadsheet software for data analysis and management. However, when it comes to exchanging data between different systems or applications, a standardized format is often required. XRDML (X-Ray Diffraction Markup Language) is a markup language used to represent X-ray diffraction data. In this paper, we discuss the process of converting Excel files to XRDML with high-quality transformation. We present a step-by-step approach to achieve this conversion, highlighting the challenges and solutions encountered during the process.
Introduction
Microsoft Excel is a popular spreadsheet software used for data analysis, management, and visualization. Its widespread adoption has made it a de facto standard for data exchange in various fields, including science, engineering, and finance. However, Excel files are not easily readable by other applications, and data exchange between different systems often requires a standardized format.
XRDML is a markup language specifically designed to represent X-ray diffraction data. It provides a structured way to describe the data, including the experimental conditions, instrument settings, and measured intensities. XRDML is widely used in the field of materials science, particularly in the analysis of X-ray diffraction data.
Conversion Challenges
Converting Excel files to XRDML poses several challenges:
Conversion Approach
To overcome the challenges mentioned above, we propose a step-by-step approach to convert Excel files to XRDML:
Implementation
We implemented the conversion approach using C# and .NET Framework. The implementation consists of the following components:
Results and Discussion
We tested the conversion approach using several Excel files with varying complexity and data quality. The results show that the conversion approach produces high-quality XRDML files, with accurate data and correct structure. The conversion process handles errors, inconsistencies, and missing values, ensuring that the output XRDML files are reliable and usable.
Conclusion
Converting Excel files to XRDML requires careful consideration of data structure, data types, and data quality. The step-by-step approach presented in this paper provides a high-quality transformation, handling errors and inconsistencies during the conversion process. The implementation using C# and .NET Framework demonstrates the feasibility of the approach, producing accurate and reliable XRDML files.

To convert Excel data ( and intensity) to the high-quality XRDML format, you must wrap the raw numerical values in a specific XML structure that includes instrument and measurement metadata. Since XRDML is a proprietary format created by Malvern Panalytical, direct conversion from Excel is typically done using specialized XRD software or dedicated conversion utilities. Top Methods for High-Quality Conversion
Malvern Panalytical HighScore Plus (Professional Choice)This is the most reliable method for maintaining data integrity. You can configure HighScore Plus to read Excel files by adding the .xlsx extension in the program settings under Customize > Program Settings > Automatic Processing. Once the Excel file is opened, you can "Save As" an XRDML file.
PowDLL Converter (Highly Recommended Utility)PowDLL is a popular, free tool in the research community specifically designed to convert between various XRD formats. It can convert a two-column Excel or CSV file (containing and intensity) directly into XRDML.
Pro Tip: Ensure your Excel file is saved in a simple two-column format without headers for the smoothest conversion.
XRDlicious (Online Platform)For a quick, web-based solution, XRDlicious allows you to upload common XRD formats or XY data and convert them to XRDML. It provides a preview of the diffraction pattern and allows you to modify header information (like wavelength) before downloading the final file.
