**publCIF** is a software application designed for creating, editing, and validating crystallographic information files (CIFs) used in journal publications. It provides syntax and dictionary-defined data attribute validation through internal routines and integrates with the *checkCIF* service of the International Union of Crystallography (IUCr) for comprehensive crystallographic analysis. The graphical interface supports editing in raw ASCII form or formatted structure reports, along with convenience tools like spreadsheet representations of looped data. Beyond validation, **publCIF** offers resources for preparing structure reports, including databases for author details, experimental data, and standard references. It also includes tools for reference parsing, spell checking, structure visualization, and image management. Optimized for single-crystal and powder CIFs describing small-molecule or inorganic structures, **publCIF** is available for Linux, MacOS, and Windows. The software is free for noncommercial use and is continuously developed based on user feedback and evolving publication requirements.**publCIF** is a software application designed for creating, editing, and validating crystallographic information files (CIFs) used in journal publications.
