public final class Extsst
extends XLSRecord

Extsst: Extended Shared String Table (FFh)
hashtable that optimizes external copy operations.

    offset  name        size    contents
    ---    
    4       Dsst        2       Number of strings in each bucket
    6       Rgisstinf   var     Array of ISSTINF Structures
    

The first WORD in each ISSTINF entry in the EXTSST record is an absolute offset into the Workbook stream. It's value isn't record dependent. The second WORD in each ISSTINF entry in the EXTSST record is the offset into the record where the string is found. In the case where the string is found in a CONTINUE record, the value should be the offset into the CONTINUE record. For example: In an Excel workbook with a lot of strings, the SST record might start at offset 0x07F2 into the Workbook stream. The next record, a CONTINUE record, starts at offset 0x2810. The first 52 ISSTINF entries in the EXTSST record work just as we would expect, with offsets into the SST record. The 53 ISSTINF entry contains an offset into the CONTINUE record, and absolute addressing continues normally. ISSTINF entries 52 and 53 look like this: ISSTINF 52 absolute offset: 0x27E5 ISSTINF 52 relative offset: 0x1FF3 ISSTINF 53 absolute offset: 0x28A4 ISSTINF53 relative offset: 0x0094 As you can see, while the absolute offset continues to increment, the relative offset resets to begin addressing from the beginning of the CONTINUE record.
