Hi hernan,
Splitting by space doesn't seem to be a suitable option because it appears at inconsistent places in each column.
At first I will suggest you try importing the text file
manually into Excel. Check the below link and see by which of the options i] Delimiters (comma, space, tab,...) or ii] Fixed Width you are able to import that file successfully. Then try to do the same using Blue Prism by seeing if there are any options to do so directly or else by writing a code, etc. If you are able to successfully import the file manually then share your findings here and someone would be able to help you with any options in BP.
