title: What does the "s" attribute signify in a cell tag in XLSX
body: <p>In the XML of a worksheet in an XLSX file (Excel 2007) cell tags  that have a "t" attribute equal to "s" are string types.  The value tag inside the c needs to be looked up and converted via the sharedStrings document.  But, some cells have s="237" and no t attribute at all.  The value tag has an integer like 39448 which does not relate to the sharedStrings document.  The value as it appears in Excel is a date 1/1/2008.  </p>
