xls2tsv
=head1 SYNOPSIS
xls2tsv file.xls > file.tsv
=head1 DESCRIPTION
This is a fairly simple-minded tool to extract content from Excel
spreadsheet files and print the cell data in plain-text tab-delimited
format. The output preserves one or more consecutive empty rows a
single blank line; within non-empty rows, each non-row-final empty
cell is preserved as a tab character.
We loop over the "worksheet" pages in the given .xls file, and output
a ";;; sheetname" line, followed by a blank line, to mark the start of
each one.
When cell data content is found to be unicode, it is printed out in
utf8 encoding. Leading and trailing spaces are discarded; any cell
found to contain only whitespace characters (including tab, and
other "wide" space characters available in unicode) is treated as
empty. Apart from these points, cell contents are output exactly as
found.
Cell and string formatting features are not preserved; changes of
foreground/background color and font style (bold, italic, underline,
etc) are ignored.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
