The first thing is that you do not have an idea about the file format. Normaly one would know the type of line break.
So we do it in general

CLEAR
#DEFINE dcCRLF	0h0D0A
#DEFINE dcCR	0h0D
#DEFINE dcLF	0h0A

lcFile = "Your File Name"
lcData = ALLTRIM(FILETOSTR(lcFile))

*We do not have an idea what file type we have
*lets figure it out
*if the line breaks are mixed, not with this programm
*this would need some more things (or a loop, but this is boring)
DO CASE
 CASE dcCRLF$lcData
* this is a CRLF File
  lcLineBreak = dcCRLF
 CASE dcCR$lcData
* this is a LF File
  lcLineBreak = dcCRLF
 CASE dcLF$lcData
* this is a LF File
  lcLineBreak = dcCRLF
 OTHERWISE
*no idea, do nothing
  lcLineBreak = .NULL.
ENDCASE

*to format all files with CRLF replace .f. with .t.
IF .F. THEN
 lcLineBrkNew = dcCRLF
ELSE  &&.F.
 lcLineBrkNew = lcLineBreak
ENDIF &&.F.

IF !ISNULL(lcLineBreak) THEN
*we found something, lets do
 lcData = STRTRAN(lcData,lcLineBreak,lcLineBrkNew+' ')
ENDIF &&!ISNULL(lcLineBreak)
?lcData
