Other than converting to a string and parsing with STRSPLIT/STRJOIN or
STRPOS/STRPUT, I wouldn't know.

Ok, thanks.
It is not optimal in my situation, because STRPUT and STRPOS accept
string arrays, but STRPUT accepts only a scalar value for the
position, so that I would need to create a FOR loop iterating over
each single value...
Is there some other solution using string formatting which would avoid
this? I copy my simple code below.
;Save a 1D or 2D array as text file with : separated values which can
be imported by Excel
PRO XLS_save, fn, data
OPENW, unit, fn, /GET_LUN
FOR i=0, (SIZE(data, /DIMENSIONS))[0]-1 DO BEGIN
printf, unit, STRJOIN(STRING(REFORM(data[i,*])), ':')
ENDFOR
CLOSE, unit & FREE_LUN, unit
END
