Just change the format from custom to General for that column.<br />
Then type &quot;MC0001&quot; in the first cell and fill it down.<br />
<br />
To remove a space you would use the following formula:<br />
<br />
=SUBSTITUTE(C1,&quot; &quot;,&quot;&quot;)

Then type "MC0001" in the first cell and fill it down.

To remove a space you would use the following formula:

=SUBSTITUTE(C1," ","")

<div>
format your column as custom format &quot;MC&quot;00000<br />
<br />
Do a search replace (Ctrl+H) on your column to search for MC and replace with nothing<br />

Well looking at the sheet your using a custom Cell format which add's in MC but doesn't actually add it to the cell.<br />
<br />
Currently its &quot;MC &quot;0000 it need's swapping to &quot;MC&quot;0000<br />
<br />
But that still won't actually put the MC into the cell as its a format option.<br />

If you want your values to be converted to text, use the formula <br />
=&quot;MC&quot; &amp;&nbsp;text(A2,&quot;0000&quot;)
</div>


If you want your values to be converted to text, use the formula
="MC" & text(A2,"0000")

Can somebody give me a clean sheet, I will study your suggestion later on.
