NAME
xlhtml - A program for converting Microsoft Excel Files .xls SYNOPSIS
xlhtml [-a] [-asc] [-csv] [-xml] [-bcNNNNNN] [-bi/path] [-c] [-dp] [-v] [-fw] [-m] [-nc] [-nh] [-tcNNNNNN] [-te] [-xc:N-N] [-xp:N] [-xr:N- N] FILE DESCRIPTION
This manual page explains the xlhtml program. The program xlhtml is used to convert Microsoft Excel Spreadsheet files into either html or tab delimitted ASCII. The program can be interfaced with helper scripts for viewing email attachments. Most use of this program is through the helper scripts and one would probably rarely resort to using the commandline interface. OPTIONS
-a aggressively optimize html by removing </TR> </TD> or VALIGN="bottom". Some older browsers may not display properly in this mode. -asc Ascii out of -dp and extraction data (-xc, -xp, -xr) -csv Output in Comma Separated Values of -dp and extraction data (-xc, -xp, -xr) -xml Output in XML of -dp and extraction data (-xc, -xp, -xr) -bc Override the background color. e.g. -bc808080 for gray -bi Use background image. e.g. -bi/home/httpd/icon/tar.gif -c Centers the tables horizontally -dp Dump page count and max columns and rows per page -v Prints program version -fw suppress formula warnings about accuracy -m No encoding for multibyte -nc tells it not to colorize the output. -nh Suppress header and body tags in html output -tc Override the text color. e.g. -tcFF0000 for red -te Trims empty rows & columns at the edges of a worksheet -xc Columns (separated by a dash) for extraction (zero based) -xp Page for extraction (zero based), one page only -xr Rows (separated by a dash) to be extracted (zero based) An example of the extraction command line is: xlhtml -fw -asc -xp:0 -xr:2-6 -xc:0-1 Test.xls The extraction output is: Formatted output of cells by column left to right, columns separated by a tab, end of row is: 0x0A, end of file: AUTHOR
