In Excel, every cell may contain a hyperlink. The HYPERLINK record refers to one cell address or a cell range where all
cells contain the same hyperlink. It is part of the Hyperlink Table in the Sheet Substream (➜4.13). Every hyperlink can
contain a text mark and a description that is shown in the sheet instead of the real link. Text marks are appended behind
a link, separated by the hash sign (“#”).
Examples for text marks: www.example.org#table1 or C:\example.xls#Sheet1!A1.
Inside of this record strings are stored in several formats. Sometimes occurs the character count, otherwise the character
array size (in 16-bit character arrays the character count is half of the array size). Furthermore some strings are zeroterminated,
others not. They are stored either as 16-bit character arrays or as 8-bit character arrays, independent of the
characters.
5.58.1 Common Record Contents
Each HYPERLINK record starts with the same data items and continues with special data related to the current type of
hyperlink. It starts with a cell range. Each cell of this range will contain the same hyperlink.

of the record data (without header) is either 32 (without description) or 36+2∙dl (with description).
