The Pipeline for Hubble Legacy Archive Grism data (PHLAG) is currently being developed as an end-to-end pipeline for the Hubble Legacy Archive (HLA). The inputs to PHLAG are slitless spectroscopic HST data with only the basic calibrations from standard HST pipelines applied; the outputs are fully calibrated, Virtuall Observatory-compatible spectra, which will be made available through a static HLA-archive. We give an overview of the various aspects of PHLAG. The pipeline consists of several subcomponents -- data preparation, data retrieval, image combination, object detection, spectral extraction using the aXe software, quality control -- which is discussed in detail. As a pilot project, PHLAG is currently being applied to NICMOS G141 grism data. Examples of G141 spectra reduced with PHLAG are shown.
