Merge break line on text file

Hi Gary,
Thanks for your notes. But the "line break" i mean is slightly different.

My raw data was in text format and there is a note column. When i open the exported data, the notes in the column has been broken in different lines so in this case when i do texttocolumn to import the data in excel the notes in the column will be brokendown vertically to servarl cells instead of having all contents in one cell.

For example:
my raw data shows the number of transations have been made. Column P is the "Note" column for each transactions. when i export the raw data. the note has been brokendown like below in text format

Note showed in the system:
"A has not pay the transaction due to ..." (all in one line)
in the exported text file:
"A has not pay the transaction
due to
..." (broken down to three lines)

So if i import it into excel, the notes will be TextToColumn in three different cells. i.e. P2 "A has not pay the transaction", P3 "due to", P3"...".

I was trying to ask if there was anyway to merge the three cell content into one cell in P2.

Hope i have made it clear. Please let me know
Thanks
Bin
