We release fully reduced spectra obtained with NIRSpec onboard JWST as part of the GLASS-JWST Early Release Science Program and a follow-up Director’s Discretionary Time program 2756. From these 263 spectra of 245 unique sources, acquired with low (R = 30–300) and high dispersion (R ∼ 2700) gratings, we derive redshifts for 200 unique sources in the redshift range z = 0–10. We describe the sample selection and characterize its high completeness as a function of redshift and apparent magnitude. Comparison with independent estimates based on different methods and instruments shows that the redshifts are accurate, with 80% differing less than 0.005. We stack the GLASS-JWST spectra to produce the first high-resolution (R ∼ 2700) JWST spectral template extending in the rest frame wavelength from 2000 Å to 20 000 Å. Catalogs, reduced spectra, and template are made publicly available to the community.
