###How to get data out of [Spectral Workbench](http://spectralworkbench)### There are CSV, XML, and JSON exports available for any spectrum, even those which haven't yet been calibrated. They are available on the "show spectrum" pages such as: https://spectralworkbench.org/spectra/show/913 Look in the "Details" section, above the social sharing badges, as in this screenshot: >

###Bulk queries You can download data in bulk on the Tag page, which includes links to recent spectra in XML or JSON format on a per-tag basis. For example: https://spectralworkbench.org/tag/laser.json https://spectralworkbench.org/tag/cfl.xml It only displays the most recent 24, but you can go back by "page" using: https://spectralworkbench.org/tag/cfl.xml?page=3 https://spectralworkbench.org/tag/cfl.xml?page=4 https://spectralworkbench.org/tag/cfl.xml?page=5 ###CSV format description### The CSV output is a 5 column comma separated text file. The first row contains text headers. Subsequent rows contain data in increasing wavelength order. Column 1 contains the wavelength in nm. Column 2 contains the average reflectance/transmittance/emissivity as a raw value integer in the range [0,255] as read. This value has not been converted to physical units and does not distinguish between reflectance and emissivity. Columns 3, 4, and 5 are in the same format as column 2 and represent the red, green, and blue channels as read from the spectrum image.
