Corrupt XLSX Salvager is designed to salvage data from
corrupt Excel 2007 - 2013 'Office Open XML' XLSX
extension files and convert worksheets to CSV format.
XLSX files are really conventionally zipped
collections of mostly XML files. The main unformatted
data is contained in the sharedStrings and numbered
worksheet XML files. XML is a very unforgiving medium
when it comes to data corruption, thus if the
sharedStrings and or worksheet XML files become even
slightly corrupt, Excel sometimes has difficulty
recovering the unformatted data.

Corrupt XLSX Salvager uses a command line unzipping
program that will unzip partially corrupt worksheet
[#].xml and sharedStrings.xml files and then utilizing
Perl regular expression data extraction routines which
don't use XML techniques that care about well-formed
XML, a stumbling block for some other Excel 2007-2013
recovery programs and for Excel itself, extract the
strings and data and put the data into the right
cells. Admittedly Excel itself now has strong data
