Excel is likely to save it as whatever it was in the first place, which is why you keep getting xml. Move your originals to xls and it'll try to keep saving them as xls.

Excel confuses this by calling everything xls. anything from xml, csv, to an actual xls file can be saved under the xls extension sometimes.

NAME
Spreadsheet::Read - Read the data from a spreadsheet SYNOPSIS
use Spreadsheet::Read; my $ref = ReadData ("test.csv", sep => ";"); my $ref = ReadData ("test.sxc"); my $ref = ReadData ("test.ods"); my $ref = ReadData ("test.xls"); my $ref = ReadData ("test.xlsx"); my $ref = ReadData ($fh, parser => "xls"); my $a3 = $ref->[1]{A3}, " "; # content of field A3 of sheet 1 DESCRIPTION
Spreadsheet::Read tries to transparently read *any* spreadsheet and return its content in a universal manner independent of the parsing module that does the actual spreadsheet scanning. For OpenOffice this module uses Spreadsheet::ReadSXC For Microsoft Excel this module uses Spreadsheet::ParseExcel or Spreadsheet::XLSX For CSV this module uses Text::CSV_XS (0.29 or up required, 0.73 or up preferred) or Text::CSV_PP (1.05 or up required). For SquirrelCalc there is a very simplistic built-in parser Data structure The data is returned as an array reference: $ref = [ # Entry 0 is the overall control hash { sheets => 2, sheet => { "Sheet 1" => 1, "Sheet 2" => 2, }, type => "xls", parser => "Spreadsheet::ParseExcel", version => 0.26, }, # Entry 1 is the first sheet { label => "Sheet 1", maxrow => 2, maxcol => 4, cell => [ undef, [ undef, 1 ], [ undef, undef, undef, undef, undef, "Nugget" ], ], A1 => 1, B5 => "Nugget", }, # Entry 2 is the second sheet { label => "Sheet 2", : : To keep as close contact to spreadsheet users, row and column 1 have index 1 too in the "cell" element of the sheet hash, so cell "A1" is the same as "cell" [1, 1] (column first). To switch between the two, there are two helper functions available: "cell2cr ()" and "cr2cell ()". The "cell" hash entry contains unformatted data, while the hash entries with the traditional labels contain the formatted values (if applicable). The control hash (the first entry in the returned array ref), contains some spreadsheet meta-data. The entry "sheet" is there to be able to find the sheets when accessing them by name: my %sheet2 = %{$ref->[$ref->[0]{sheet}{"Sheet 2"}]}; Functions my $ref = ReadData ($source [, option => value [, ... ]]); my $ref = ReadData ("file.csv", sep => ',', quote => '"'); my $ref = ReadData ("file.xls", dtfmt => "yyyy-mm-dd"); my $ref = ReadData ("file.ods"); my $ref = ReadData ("file.sxc"); my $ref = ReadData ("content.xml"); my $ref = ReadData ($content); my $ref = ReadData ($fh, parser => "xls"); Tries to convert the given file, string, or stream to the data structure described above. Processing Excel data from a stream or content is supported through a File::Temp temporary file or IO::Scalar when available. ReadSXC does preserve sheet order as of version 0.20. Currently supported options are: parser Force the data to be parsed by a specific format. Possible values are "csv", "prl" (or "perl"), "sc" (or "squirelcalc"), "sxc" (or "oo", "ods", "openoffice") "xls" (or "excel"), and "xlsx" (or "excel2007"). When parsing streams, instead of files, it is highly recommended to pass this option. cells Control the generation of named cells ("A1" etc). Default is true. rc Control the generation of the {cell}[c][r] entries. Default is true. attr Control the generation of the {attr}[c][r] entries. Default is false. See "Cell Attributes" below. clip If set, "ReadData ()" will remove all trailing lines and columns per sheet that have no visual data. This option is only valid if "cells" is true. The default value is true if "cells" is true, and false otherwise. strip If set, "ReadData ()" will remove trailing- and/or leading-whitespace from every field. strip leading strailing ----- ------- --------- 0 n/a n/a 1 strip n/a 2 n/a strip 3 strip strip sep Set separator for CSV. Default is comma ",". quote Set quote character for CSV. Default is """. dtfmt Set the format for M$Excel date fields that are set to use the default date format. The default format in Excel is 'm-d-yy', which is both not year 2000 safe, nor very useful. The default is now 'yyyy-mm-dd', which is more ISO-like. Note that date formatting in M$Excel is not reliable at all, as it will store/replace/change the date field separator in already stored formats if you change your locale settings. So the above mentioned default can be either "m-d-yy" OR "m/d/yy" depending on what that specific character happened to be at the time the user saved the file. debug Enable some diagnostic messages to STDERR. The value determines how much diagnostics are dumped (using Data::Dumper). A value of 9 and higher will dump the entire structure from the back-end parser. Using CSV In case of CSV parsing, "ReadData ()" will use the first line of the file to auto-detect the separation character if the first argument is a file and both "sep" and "quote" are not passed as attributes. Text::CSV_XS (or Text::CSV_PP) is able to automatically detect and use " " line endings). CSV can parse streams too, but be sure to pass "sep" and/or "quote" if these do not match the default "," and """. Functions my $cell = cr2cell (col, row) "cr2cell ()" converts a "(column, row)" pair (1 based) to the traditional cell notation: my $cell = cr2cell ( 4, 14); # $cell now "D14" my $cell = cr2cell (28, 4); # $cell now "AB4" my ($col, $row) = cell2cr ($cell) "cell2cr ()" converts traditional cell notation to a "(column, row)" pair (1 based): my ($col, $row) = cell2cr ("D14"); # returns ( 4, 14) my ($col, $row) = cell2cr ("AB4"); # returns (28, 4) my @row = row ($ref, $row) my @row = Spreadsheet::Read::row ($ss->[1], 3) Get full row of formatted values (like "$ss->{A3} .. $ss->{G3}") Note that the indexes in the returned list are 0-based. "row ()" is not imported by default, so either specify it in the use argument list, or call it fully qualified. my @row = cellrow ($ref, $row) my @row = Spreadsheet::Read::cellrow ($ss->[1], 3) Get full row of unformatted values (like "$ss->{cell}[1][3] .. $ss->{cell}[7][3]") Note that the indexes in the returned list are 0-based. "cellrow ()" is not imported by default, so either specify it in the use argument list, or call it fully qualified. my @rows = rows ($ref) my @rows = Spreadsheet::Read::rows ($ss->[1]) Convert "{cell}"'s "[column][row]" to a "[row][column]" list. Note that the indexes in the returned list are 0-based, where the index in the "{cell}" entry is 1-based. "rows ()" is not imported by default, so either specify it in the use argument list, or call it fully qualified. parses ($format) Spreadsheet::Read::parses ("CSV") "parses ()" returns Spreadsheet::Read's capability to parse the required format. "parses ()" is not imported by default, so either specify it in the use argument list, or call it fully qualified. my $rs_version = Version () my $v = Spreadsheet::Read::Version () Returns the current version of Spreadsheet::Read. "Version ()" is not imported by default, so either specify it in the use argument list, or call it fully qualified. Cell Attributes If the constructor was called with "attr" having a true value, effort is made to analyze and store field attributes like this: { label => "Sheet 1", maxrow => 5, maxcol => 2, cell => [ undef, [ undef, 1 ], [ undef, undef, undef, undef, undef, "Nugget" ], ], attr => [ undef, [ undef, { type => "numeric", fgcolor => "#ff0000", bgcolor => undef, font => "Arial", size => undef, format => "## ##0.00", halign => "right", valign => "top", uline => 0, bold => 0, italic => 0, wrap => 0, merged => 0, hidden => 0, locked => 0, enc => "utf-8", }, ] [ undef, undef, undef, undef, undef, { type => "text", fgcolor => "#e2e2e2", bgcolor => undef, font => "Letter Gothic", size => 15, format => undef, halign => "left", valign => "top", uline => 0, bold => 0, italic => 0, wrap => 0, merged => 0, hidden => 0, locked => 0, enc => "iso8859-1", }, ] A1 => 1, B5 => "Nugget", }, This has now been partially implemented, mainly for Excel, as the other parsers do not (yet) support all of that. YMMV. TODO
Options Module Options New Spreadsheet::Read options are bound to happen. I'm thinking of an option that disables the reading of the data entirely to speed up an index request (how many sheets/fields/columns). See "xlscat -i". Parser options Try to transparently support as many options as the encapsulated modules support regarding (un)formatted values, (date) formats, hidden columns rows or fields etc. These could be implemented like "attr" above but names "meta", or just be new values in the "attr" hashes. Other spreadsheet formats I consider adding any spreadsheet interface that offers a usable API. Add an OO interface Consider making the ref an object, though I currently don't see the big advantage (yet). Maybe I'll make it so that it is a hybrid functional / OO interface. SEE ALSO
