Text Column

"<td style=\"mso-number-format:'\@'\">"

or

<td style="mso-number-format:'\@'">

Answer 2

It doesn't works sometimes if you add it using a css class in that case try it using in Style to your TD. I did it for formatting a column to a text. like this

 style="mso-number-format:\@;"

For you it would be as

  mso-number-format:General

Answer 3

UPDATE: You also need to remove non-breaking spaces (nbsp's) from td cells containing numeric or money information to make formulas work on these cells in Excel. So the problem is solved.

Answer 4

I couldn't get any of the answers on this page to work in Excel 2010. I ended up using this.

<td x:num>123</td>

Answer 5

If you add a CSS Class to your page:

.num {
  mso-number-format:General;
}
.date {
  mso-number-format:"Short Date";
}

And slap those classes on your TD's, does it work?

<td class="num">34</td>
<td class="num">17.0</td>
<td class="date">12/17/2008</td> <!-- if you are playing with dates too -->

Update: Additional formatting options from @Aaron.
