This is what the input data file looks like with broken lines

Expected format after transformation should look like this

I'm still lost. Please describe in English the transformations that you are trying to make.

It appears that you want to remove leading and trailing spaces in a field, but keep spaces in the middle of a field.

It appears that you want to join all sets of adjacent lines that contain any field separators. (Is it all adjacent input lines, or pairs of input lines that are to be joined?)

Will blank or empty lines separate each set of lines that you want to join?

It appears that you want to leave lines with no field separators unchanged. (In your example there is a blank line. Does this also apply to empty lines?)

I see no pattern that would explain why the 01<space> marked in red in input.txt was removed in output.txt. Please explain in English what the logic is for removing non-<space> characters from some fields!

If two lines to be joined don't have a field separator as the last character of the first line or as the first character of the second line, is anything supposed to be added to the line where the lines are joined? (Perhaps a <space> character?)

Test::use::ok(3)					User Contributed Perl Documentation					  Test::use::ok(3)

NAME
Test::use::ok - Alternative to Test::More::use_ok SYNOPSIS
use ok 'Some::Module'; DESCRIPTION
According to the Test::More documentation, it is recommended to run "use_ok()" inside a "BEGIN" block, so functions are exported at compile-time and prototypes are properly honored. That is, instead of writing this: use_ok( 'Some::Module' ); use_ok( 'Other::Module' ); One should write this: BEGIN { use_ok( 'Some::Module' ); } BEGIN { use_ok( 'Other::Module' ); } However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other tests in a single "BEGIN" block, which can create subtle differences in execution order. With this module, simply change all "use_ok" in test scripts to "use ok", and they will be executed at "BEGIN" time. The explicit space after "use" makes it clear that this is a single compile-time action. SEE ALSO
