    Bruker .raw (versions 1–4) or .brml, PANalytical .xrdml, Rigaku .ras/.rasx/.asc, 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

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

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

    More options

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

    Your files are deleted after processing.

    Rigaku SmartLab, MiniFlex and Ultima diffractometers save measurements as .ras text files, .rasx archives from SmartLab Studio II, or .asc exports from PDXL. This page reads all three and returns .xy, .xye, CSV, Excel or XRDML files, without SmartLab Studio or PDXL.

    How to convert RAS or RASX to XY

    1. Upload the .ras, .rasx or .asc file; a whole folder can go in as a ZIP.
    2. Choose the x axis (2θ as measured, d-spacing, Q or Cu-equivalent 2θ) and the intensity (counts, counts per second, or normalised to 100).
    3. Download the .xy for plotting or phase identification, or the .xye for Rietveld refinement.

    What the converter takes care of

    • Attenuator factors. RAS and RASX files store a third column with the attenuator factor for each point. The intensity in the output is counts × factor, so strong peaks measured with the attenuator in place come out at the right height.
    • Japanese and English text. RAS headers are Shift-JIS text and many values are pairs such as "日本語|English". The English part is kept for the metadata.
    • Counting time. Rigaku stores scan speed in degrees per minute rather than time per step. The time per step is worked out from step and speed, which is what Counts per second uses.
    • Several profiles. Files with more than one data block give one scan each; the .xy holds the first, and a ZIP holds them all.

    Metadata you can check

    The preview lists the instrument model, measurement date, anode, Kα1, Kα2 and Kβ wavelengths, 2θ range, step, number of points, time per step, detector (for example a HyPix3000), attachment, scan axis and mode, scan speed and generator voltage and current. The Excel workbook includes the same list on a metadata sheet.

    Accuracy

    A SmartLab .ras conversion was identical to the SmartLab .xy and PDXL .asc exports of the same measurement, and RAS files also matched the independent xrayutilities reader.

    Files that won't convert

    • Rigaku's binary .raw format is recognised but not supported; export .ras or .xy from the Rigaku software instead.
    • A .rasx that contains only 2D detector images needs integrating to a 1D profile first.

    To compare your Rigaku data with Cu reference patterns from a different tube, or to plot it against d-spacing, see 2θ to d-spacing. Other formats: XRDML to XY, Bruker RAW to XY.
