JWST NIRCam, Euclid NISP, and Roman WFI photometry (apparent magnitudes) for 800+ ultracool dwarfs synthesized using near-IR SpeX prism spectra. This is a supplementary data product to Sanghi et al. 2023 (RNAAS, 7, 194) and Sanghi et al. 2024 (RNAAS, 8, 137). JWST photometry is presented in the Vega magnitude system and Euclid and Roman photometry are presented in the AB magnitude system. For research that benefits from this compilation, please cite Sanghi et al. 2023 (RNAAS, 7, 194) for JWST photometry, Sanghi et al. 2024 (RNAAS, 8, 137) for Euclid and Roman photometry, and include the following acknowledgment: "This work has benefitted from The UltracoolSheet, maintained by Will Best, Trent Dupuy, Michael Liu, Aniket Sanghi, Rob Siverd, and Zhoujian Zhang, and developed from compilations by Dupuy & Liu (2012, ApJS, 201, 19), Dupuy & Kraus (2013, Science, 341, 1492), Liu et al.
