3 Structure Examples


This section contains examples of some of the most commonly used data structures in Excel Binary File Format files. The examples are meant to be a starting point for an implementer learning the file format. They are not meant to cover all records in the file format.

The following conventions are followed for all of the examples, unless noted otherwise:

  • The order of the records, structures, and field within the example match their corresponding order in the file format.

  • The examples begin with the first record relevant to the example and end with the last record relevant to the example. An example cannot be used as a complete and standalone MS-XLSB file.

  • The examples are self-contained and contiguous; no records or structures are omitted in the middle of an example.

  • Undefined and ignored fields are not included in the field explanations.

  • Offsets for records and structures are omitted because these values can vary depending on how the files are created and what optional records applications choose to include in files.
