What are CBXML files and how to open them

Are you having problems opening a CBXML file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your CBXML files.

What is a CBXML file?

A .CBXML file is a CodeBox Snippet Library file.

CodeBox Snippet Library is a file format used by CodeBox, a code snippet manager developed by Vadim Shpakovski, to store collections of code snippets. It serves as the central store for organizing, editing, sharing, and archiving snippets, along with metadata such as folders, tags, asset files, modification times, and other descriptors.

The format stores every snippet library as a single document structured in XML. Snippets are grouped by folder (or project), and include attachments ("assets"), tags, and search definitions. Each snippet entry contains fields for content, notes, language or type, locking or expansion state, sorting order, parent/child relations among items, and timestamps. Libraries written in this format may be imported or exported for sharing, backup, or migration between snippet management tools.

Technical identification includes starting byte sequence 3C 3F 78 6D 6C 20 76 65 72 73 69 6F 6E 3D 22 31 2E 30 22 20 73 74 61 6E 64 61 6C 6F 6E 65 3D 22, which corresponds to an XML declaration with version 1.0 and standalone attribute. The file contains internal XML keys such as NSSTOREMODELVERSIONHASHESVERSION, NSPERSISTENCEFRAMEWORKVERSION, DOCTYPE DATABASE SYSTEM, and elements like ALL SNIPPETS, RELATIONSHIP NAME, ATTRIBUTE NAME, LIBRARY, ASSETS, FOLDER, UUID, CONTENT, and CHILDREN among others.
