1.3 Overview

This document specifies workbook data contained in a compound file as described in [MS-CFB]. The data is stored in the compound file by using storages, streams (section 2.1.2), and substreams (section 2.1.3) that contain information about the content and structure of a workbook, including workbook data such as worksheet definitions. Some storages, streams, and substreams store information by using binary records (section 2.1.4). The binary record (section 2.1.4) structure and content are specified in this document. Each binary record contains its record type, information about the record size, and zero or more type-specific fields depending on the record type, which is specified in section 2.3. Type-specific fields contain information further specifying the workbook data. Specifications of the fields for a given record type can be found in section 2.4.

See the File Structure section (section 2.1) for a more detailed overview of specific file architecture and content.
