How To Split Texts Into Words (collecting Word And Compounds)

i have wordlists which i would like to enhance through texts. For that purpose i need a macro which reads a text and splitts it into words and put the words into three columns. Lets assume the column where the words are supposed to be put is columns A,C and E. The column A should contain single words containing no spaces from Text, column C should contain compound words which have one space between them and in column E those compounds which have two spaces. Now i will put my existing wordlist in column G before i start splitting texts. The macro should put only those words from text into column A,C and E which dont already exist in columns A,B,C,D,E,F and G. In Column B i will place the corrected or checked words from column A. In column D i will type the corrections and checked versions of those compunds existing in column C. And the column F will contain the compound words which are corrected and checked from Column E.

Column A--> single words splitted from text through macro (containing no spaces)
Column B--> corrected and checked versions of words from column A through user
Column C--> compound words containing one space splitted from text through macro (for example:"etwas möchten" or "do something")
Column D-->corrected version of C through user
Column E-->compound words containing two space splitted from text through macro (for example:"sich uerberzeugen lassen" or "down in dumps")
Column F-->corrected E
Column G--> existing dictionary wordlist through user

Signes like ".", ":",";", "/" or quotation signe itself should be seen as seperator. And the words or compounds splitted from the text should not contain these signs.

The text will be put in another sheet in the same excel file. Lets call that sheet "text". The macro should search for words through whole sheet ignoring empty cells or columns.

None of the columns should be filtered or ordered. The columns shound not be deleted as well. That way the user wont have to correct the same word each time cus the corrected as well as the original words will be there.

A thread with similar purpose was made sent by AdamDay as well, where rylo has posted a good solution already.
