The HXL Proxy is a tool for validating, cleaning, transforming, and visualising HXL-tagged data. You supply an input url pointing to a tabular or JSON dataset and then create a recipe that contains a series of steps for transforming the data. The result is a download link that you can share and use in HDX, and the output will update automatically whenever the source dataset changes. Full user documentation is available in the HXL Proxy wiki. The HXL Proxy is primarily a web wrapper around the libhxl-python library (see above), and makes the same functionality available via RESTful web calls.
