You should be able to import the Excel file into html, then strip out anything Excel-specific, leaving only the values and the tags html uses to create the table:
<table></table> (table) or
<tr></tr> (table row) or
<td></td> (table cell).
The structure will look like:
Code:
<table>
<tr>
<td> your 1st col</td>
<td> your 2nd col</td>
<td> your 3rd col</td>
<td> your 4th col</td>
</tr>
The above will be repeated 1700 times (once for each of your rows) then the end table tag
</table>
If you have W2K or XP, Notepad can do a Find... Edit... Replace and you can manually strip out all the extra Excel junk.
