This paper reports on the scientific pipeline for the analysis of the ECLAIRs data of the Space-based multi-band Variable Objects Monitor mission. We describe the overall procedure, the different steps and the main algorithms of the data analysis for this hard X-ray coded mask instrument. The pipeline runs in automatic mode at the science center generating standard products but can also be used offline with specific choices of parameters. Generated data products and preliminary performances are illustrated along with perspectives for future improvements.
