csv import -checkbox formatting question

I have a form saving info to a csv file. Later, I want to import the csv file into cmsb. For the checkboxes, what values should I use to have them checked or unchecked in cmsb after importing later (since i can only use strings)?

Currently, I am using this for the checkboxes in my form:


<tr>
<td align="right">Interested In:</td>
<td>&nbsp;</td>
<td><input type="hidden" name="tastings" value="false" />
<label><input type="checkbox" name="tastings" value="true" />Pre-Opening Food Tastings</label>
</td>
</tr>

<tr>
<td align="right">&nbsp;</td>
<td>&nbsp;</td>
<td align="left" valign="top"><input type="hidden" name="coupons" value="false" />
<label><input type="checkbox" name="coupons" value="true">Discount Coupons</label>
</td>
</tr>

Which results in those cells in csv / excel being true or false strings. Will this result in checked or unchecked boxes in cmsb? hmmm... As i am writing this, i am thinking i should use the strings, 0 or 1. ? Will cmsb check boxes on import? unfortunately, that isnt as pretty in the e-mail that is also being sent for now to the client:

Interested in:
Pre-Opening Tastings
false

Discount Coupons
true

Anyway, please let me know the best way to handle this for now to get a nice import later when i make some type of newsletter subscription editors (example: coupon email list for all those marked "true")
