Hello Monks..!!
Hope all doing good :)
I am trying to Get Excel column name for given decimal number.
my code able to obtion from A..ZZ. Once it reaches column AAA its not working. I have to update logic but I am running out of ideas.
Also I felt my code is very long. So any ideas to improve my code is appreciated.
Here is my code:
.
$colname = GetExcelColumnName(703);
print "colname is : $colname \n";
sub GetExcelColumnName
{
$columnNumber = $_[0];
$columnnamestr = "";
print "column number is : $columnNumber \n";
$columnNumber = $columnNumber;
$div = $columnNumber/26;
my $divstart = 0;
if($columnNumber%26 == 0)
{
$div = $div - 1;
$divstart = 1;
}
$divcnt = 0;
if($div >= 1)
{
$divcnt = $columnNumber/26;
}
if(($divcnt == 0))
{
$columnname = 65-1+$columnNumber;
$return_str = chr($columnname);
}
else
{
if($columnNumber == 26)
{
$columnname = 65+$div;
}
else{
$columnname = 65-1+$div;
}
$return_str = chr($columnname);
$mod = $columnNumber%26;
if($columnname <= 90)
{
if(($return_str != 'Z') && ($mod == 0))
{
$columnname = 65;
}
elsif(($return_str == 'Z') && ($mod == 0))
{
$columnname = 90;
}
else{
$columnname = 65-1+$mod;
}
$return_str = $return_str.chr($columnname);
}
else
{
$return_str = "update logic \n";
}
}
return $return_str;
}

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).
