XLSX Excel Spreadsheets are different than the XLS version in that they use the Microsoft Office Open XML format.

It was first published anonymously in Paris in 1697 in Histoires ou contes du temps passe (PassÃ©: English stories Or tales Of Past), times a collection of eight fairy tales By. perrault
Today the book is better known as Mother Goose Tales. Seven of its eight tales have become classics for children. I'm sure that you know some of these: The Sleeping Beauty in the Wood (Sleeping Beauty), Little Red Riding Hood, Blue Beard, The Master Cat: or Puss in Boots, Diamonds and Toads, and Cinderella. Perrault, however, did not write any of these stories. They were all re-workings of stories passed from one generation to the next. These stories were actually very cruel and downright nasty in their original form. Perrault simply cleaned them up and let everyone live happily ever after.
