Bruker .raw (versions 1–4) or .brml, PANalytical .xrdml, Rigaku .raw/.ras/.rasx/.asc/.dat, Shimadzu .raw, Philips .rd/.sd/.udf, Bruker .uxd, GSAS .gsa/.fxye or .xy/.xye text. Several files or a .zip can be combined into one table.

Options

X axis

Convert 2θ with the wavelength stored in the file (Kα1).

Intensity

Counts per second divide by the counting time per step stored in the file.

More options

Start angle (°2θ) for files without angles

Only for text files that hold a single column of intensities: the 2θ of the first point. Leave empty otherwise.

Step size (°) for files without angles

Only for single-column intensity files: the angle between two points, for example 0.02.

CSV number format

Pick the comma version if your Excel uses a decimal comma (most of Europe).

Your files are deleted after processing.

Open XRD files without DIFFRAC.EVA, HighScore or SmartLab Studio

Powder diffractometers save their measurements in vendor formats that only the instrument software reads well. This converter opens Bruker, Malvern Panalytical/Philips, Rigaku, Shimadzu and GSAS files directly and gives you the pattern as a two-column .xy, an .xye with uncertainties for Rietveld refinement, a CSV and an Excel workbook with a chart, plus a standard XRDML file that HighScore, GSAS-II and Profex open.

What to upload

Instrument / software	Files	What is read
Bruker D2 PHASER, D8 ADVANCE/DISCOVER (DIFFRAC.SUITE, DIFFRAC plus, Diffrac-AT)	`.brml` (the usual ZIP and the single-XML file), `.raw` (all four versions: `RAW4.00`, `RAW1.01`, `RAW2`, `RAW` ), `.uxd`, DIFFRAC text exports	every range/scan, wavelengths and anode, step, counting time, generator, drives; temperature of each range in non-ambient series
Malvern Panalytical Empyrean, Aeris, X'Pert (Data Collector, HighScore)	`.xrdml` (versions 1.0–2.3), `.rd`/`.sd`, `.udf`, HighScore CSV exports	all scans (2θ, ω, φ … scans), attenuation factors, counting time, tube, wavelengths
Rigaku SmartLab, MiniFlex, Ultima, ATX (SmartLab Studio, PDXL)	`.ras`, `.rasx`, `.asc`, `.dat` text, binary `.raw`	all blocks/profiles and ranges, attenuator factors, scan speed and time per step, tube and wavelengths, slits, detector
Shimadzu (XRD software)	binary `.raw`	the 2θ scan, anode and wavelength, tube voltage and current, slits, scan mode, scan speed and time per step
GSAS / Rietveld	`.gsa`, `.gsas`, `.xra`, `.fxye`, `.xye`, `.xy`	constant-wavelength banks (STD, ESD, FXYE), plain columns
Intensities only	`.xy`, `.txt`, `.dat` with one number per line	the counts, placed on the 2θ scale from the start angle and step you enter under More options

Upload the file the diffractometer software saved. Several files, or a .zip of a folder, can be converted together.

What you get

.xy: angle and intensity, space-separated, no header: opens in every analysis program.
.xye: adds the standard uncertainty (√counts, or the value stored in the file).
CSV: all scans of the file with units in the header; choose the decimal-comma version if your Excel uses one.
Excel workbook: each scan with a ready-made chart, all scans on one sheet, and a metadata sheet with every setting found in the file.
XRDML: a PANalytical XRDML 1.5 file with the original angles, counts, counting time and wavelengths, valid against PANalytical's published schema.
Picture: a PNG plot of the pattern (1600 × 1000 pixels) with labelled axes, ready for a lab report or a slide.
Conversions: d-spacing, Q, or 2θ recalculated for Cu Kα1 (handy for comparing a Co- or Mo-tube pattern with Cu reference data), and counts per second or normalised intensities.

When you upload several files, you also get a combined table and workbook, one picture with all patterns, and ZIPs of the .xy/.xye and XRDML files for every file.

How accurate is it?

The Bruker, Panalytical and Rigaku readers were compared point by point with exports made by the vendor software from the same measurement (DIFFRAC text and .xy exports, XCH .uxd files, HighScore CSV and .xy exports, SmartLab .xy and PDXL .asc exports) and with the independent GSAS-II and xrayutilities readers. Counts agree exactly and angles to the last digit the exports print. The only difference you may see is in Philips .rd files, which store counts in a compressed form that rounds them by up to 0.5 %; that is how the format works, and we say so in the file details. Shimadzu .raw support is new: its angles are checked against the start, end and step stored in the file, but no Shimadzu export of the same measurement has been available yet to compare the counts with.

Privacy

Files are processed on our server only to produce your downloads. Uploads are deleted when the conversion finishes and results are deleted automatically after 30 minutes.

Not supported yet

STOE WinXPOW .raw files are recognised and reported as not supported; export them as .xy in WinXPOW for now. 2D detector images must be integrated to a 1D pattern first.

Frequently asked questions

Do I need DIFFRAC.EVA, HighScore or SmartLab Studio?

No. The files are decoded directly on our server, so any computer with a browser works. The Bruker, Panalytical and Rigaku readers were checked against exports made by the vendor software from the same measurement.

Which Bruker .raw versions work?

All four: the DOS-era Diffrac-AT files ("RAW " and "RAW2"), DIFFRAC plus ("RAW1.01") and DIFFRAC.SUITE ("RAW4.00"), including files with several ranges (e.g. temperature series). Newer measurements are stored as .brml, which is also supported.

Can I convert Shimadzu .raw files?

Yes: the binary .raw files saved by Shimadzu's XRD software, with one 2θ range. You get the pattern with its wavelength, anode, tube voltage and current, slits, scan speed and time per step. Shimadzu, Bruker and Rigaku .raw files are told apart by their content. Files with several ranges are reported as not supported yet; export those as text in the Shimadzu software.

What is the difference between .xy and .xye?

An .xy file has two columns: angle and intensity. An .xye file adds a third column with the standard uncertainty of each intensity (the square root of the counts, or the value stored in the file), which Rietveld programs such as GSAS-II, TOPAS and FullProf use for weighting.

Can I convert my Co or Mo pattern to Cu 2θ?

Yes. Choose “2θ recalculated for Cu Kα1” under X axis: every angle is converted with Bragg's law using the Kα1 wavelength stored in your file, so peak positions line up with Cu reference patterns. d-spacing and Q are available too.

Can I open the result in HighScore, GSAS-II or Profex?

Yes. Besides .xy/.xye we write a PANalytical XRDML 1.5 file with the original angles, counts, counting time and wavelengths. Every XRDML file we produce validates against PANalytical's published XML schema and was read back with the GSAS-II and xrayutilities importers.

Can I convert many files at once?

Yes: select up to 200 files or upload a .zip. The preview shows all patterns, and you get a combined table and workbook plus ZIPs of the .xy/.xye and XRDML files.

What happens to my files?

They are processed on our server only to produce your downloads and are deleted automatically after the job expires. We do not look at, keep or share your data.
