If you ever have to edit a post that contains a Table, the header row will be replaced by the column 1, column 2 etc,
just click edit again and delete those words from the row. Also watch out for Ampersands in edited posts, they will be changed to just edit them as well.
If you ever have a CSV that contains an Apostrophe you will need to Find and Replace before using the converter, if you don't... the converter will treat then as a space... and displace the Cell contents. Hardly ever a problem though. Haha first world problems... think I need a nap.
