Forcing numeric values as text on HTML table exporting to excel
Just add one line before your table
Response.Write("<style> TD { mso-number-format:\@; } </style>");Check this out: Export Gridview to Excel with rows formatted as text
Maybe try ="00212704"
Response.Write("<td class='tdsmall' align='left' NOWRAP>=""" & rsPODetail("ITM_ID") & """</td>")
One option that doesn't require modifying the content of the tables is to use the mso-number-format CSS style, as described on this SO answer. For text, you would use something like:
CSS:
.xlText { mso-number-format: "\@";}HTML:
<td class="xlText">00030</td>
