Assumption is the mother of all FU's
The danger in your remark is the word usually. Been there done that. And even if the data you are dealing with initially had a header row, there is no guarantee that the next time you get that data from external sources will have (the same) header line or that they either left it out, changed the order, spelling, casting or even inserted line(s) before the header to add "comments" or "instructions". Excel is likely one of the most misused/abused end-user tools in the (ICT) world. I *never* assumer anything in Excel, not even correct encoding or default (date) formatting.
Enjoy, Have FUN! H.Merijn

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).

or How to display code and escape characters
are good places to start.
