        This isn’t exactly the solution, but your request seems very similar to one made very recently. If you’d like to read this thread you may well find the method of doing what you want.

          Hello, @jack, @terry-r and All,

          Terry, I think that the post, that you provided, may be too complicated for noob people to regexes !

          So, here a more easy solution for the @Jack’s specific problem !

          Jack, read this post thoroughly before doing any manipulation !

          Starting with your INPUT text, below :

          00021  |03/01/2022|RECIBOS M.N.   |0661 |
 J4437            0011 0194
 J4502            0011 0194
 M077             0011 0182
 M111             0011 0355
00024  |03/01/2022|RECIBOS M.N.   |0661 |
 7260             0011 0194
 7378             0011 0486
00027  |03/01/2022|RECIBOS M.N.   |0661 |
 A1109            0011 0127
 A174             0011 0486
 A231             0011 0660
00050  |03/01/2022|RECIBOS M.N.   |0661 |
00053  |03/01/2022|RECIBOS M.N.   |0661 |
 A174             0011 0486
 A231             0011 0660
          • To begin with, add a final line-break \r\n at the very end of this INPUT file

          Then, with this first regex S/R, we’re going to invert each ligne beginning with a digit with the next existing group of lines beginning with a space character :

          • SEARCH (?x-s) ^ ( \d .+ \R ) ( (?: \x20 .+ \R )+ )

          • REPLACE \2\1

          We get this temporary OUTPUT text :

           J4437            0011 0194
 J4502            0011 0194
 M077             0011 0182
 M111             0011 0355
00021  |03/01/2022|RECIBOS M.N.   |0661 |
 7260             0011 0194
 7378             0011 0486
00024  |03/01/2022|RECIBOS M.N.   |0661 |
 A1109            0011 0127
 A174             0011 0486
 A231             0011 0660
00027  |03/01/2022|RECIBOS M.N.   |0661 |
00050  |03/01/2022|RECIBOS M.N.   |0661 |
 A174             0011 0486
 A231             0011 0660 
00053  |03/01/2022|RECIBOS M.N.   |0661 |

          Now, with this second regex S/R, we add the corresponding header, in front of each line beginning with a space char :

          • SEARCH (?x-s) ^ \x20 .+ \R (?= (?: \x20 .+ \R )* ( \d+ .+ ) )

          • REPLACE \1$0

          And our temporary OUTPUT text becomes :

          00021  |03/01/2022|RECIBOS M.N.   |0661 | J4437            0011 0194
00021  |03/01/2022|RECIBOS M.N.   |0661 | J4502            0011 0194
00021  |03/01/2022|RECIBOS M.N.   |0661 | M077             0011 0182
00021  |03/01/2022|RECIBOS M.N.   |0661 | M111             0011 0355
00021  |03/01/2022|RECIBOS M.N.   |0661 |
00024  |03/01/2022|RECIBOS M.N.   |0661 | 7260             0011 0194
00024  |03/01/2022|RECIBOS M.N.   |0661 | 7378             0011 0486
00024  |03/01/2022|RECIBOS M.N.   |0661 |
00027  |03/01/2022|RECIBOS M.N.   |0661 | A1109            0011 0127
00027  |03/01/2022|RECIBOS M.N.   |0661 | A174             0011 0486
00027  |03/01/2022|RECIBOS M.N.   |0661 | A231             0011 0660
00027  |03/01/2022|RECIBOS M.N.   |0661 |
00050  |03/01/2022|RECIBOS M.N.   |0661 |
00053  |03/01/2022|RECIBOS M.N.   |0661 | A174             0011 0486
00053  |03/01/2022|RECIBOS M.N.   |0661 | A231             0011 0660 
00053  |03/01/2022|RECIBOS M.N.   |0661 |

          Finally, with this third regex S/R, we invert, again, an existing group of lines not ending with the pipe | character and the next line ending with the pipe | character :

          • SEARCH (?x-s) ^ ( (?: .+ [^|\r\n] \R )+ ) ( .+ \| \R )

          • REPLACE \2\1

          And here is your expected OUTPUT text :

          00021  |03/01/2022|RECIBOS M.N.   |0661 |
00021  |03/01/2022|RECIBOS M.N.   |0661 | J4437            0011 0194
00021  |03/01/2022|RECIBOS M.N.   |0661 | J4502            0011 0194
00021  |03/01/2022|RECIBOS M.N.   |0661 | M077             0011 0182
00021  |03/01/2022|RECIBOS M.N.   |0661 | M111             0011 0355
00024  |03/01/2022|RECIBOS M.N.   |0661 |
00024  |03/01/2022|RECIBOS M.N.   |0661 | 7260             0011 0194
00024  |03/01/2022|RECIBOS M.N.   |0661 | 7378             0011 0486
00027  |03/01/2022|RECIBOS M.N.   |0661 |
00027  |03/01/2022|RECIBOS M.N.   |0661 | A1109            0011 0127
00027  |03/01/2022|RECIBOS M.N.   |0661 | A174             0011 0486
00027  |03/01/2022|RECIBOS M.N.   |0661 | A231             0011 0660
00050  |03/01/2022|RECIBOS M.N.   |0661 |
00053  |03/01/2022|RECIBOS M.N.   |0661 |
00053  |03/01/2022|RECIBOS M.N.   |0661 | A174             0011 0486
00053  |03/01/2022|RECIBOS M.N.   |0661 | A231             0011 0660

          For all these searches/replacements :

          • Move at the very beginning of your file

          • Open the Replace dialog ( Ctrl + H )

          • Uncheck all box options

          • Insert the corresponding search and replace regexes in the Find what : and Replace with : fields

          • Select the Regular expression search mode

          • Click once on the Replace All button ( or several times on the Replace button )

          If you need some explanations on these regexes, just tell me !

          Best Regards,

            Hi, @jack, @terry-r and All,

            Later, I realized that my first regex S/R, provided in my previous post, could be changed into this one:

            • SEARCH (?x-s) ^ ( .+ \| \R ) ( (?: .+ [^|\r\n] \R )+ )

            • REPLACE \2\1

            So, with this first regex S/R and the initial INPUT text :

            We’re going to invert each line ending with a pipe | character and the next existing group of lines not ending with a pipe | character

            In this way, just note that this NEW first regex S/R is the true opposite of the third regex S/R :-;

            BR

              Hi! @guy038 Thank you very much for your support. However, I have an issue, as I was reviewing all the cases, I found new scenarios that do not fit the previous ones. I would appreciate it if you could help me with this case.

                Not an answer, but a hint: guy038 mentioned in various places that he wanted to match lines beginning with a digit. The regex he used to match a digit was \d. Read a little bit about regular expressions and see if you can find how to match something besides a digit.

                  Hi, @jack, @terry-r, @mark-olson and All,

                  OK : I understood what happened. You have some trailing spaces at the end of some lines of your INPUT text !

                  Moreover, some header lines do not begin with digits but with word characters, so we need \w+ ( instead of \d+ )

                  So, starting with your INPUT text :

                  Before the main regexes S/R to perform, first run this simple S/R which deletes any trailing horizontal blank character :

                  SEARCH \h+$

                  REPLACE Leave EMPTY

                  You’ll get this temporary OUTPUT text :

                  Then, with this first regex S/R :

                  SEARCH (?x-s) ^ ( .+ \| \R ) ( (?: \x20 .+ \R )+ )

                  REPLACE \2\1

                  Now, with the second regex S/R :

                  SEARCH (?x-s) ^ \x20 .+ \R (?= (?: \x20 .+ \R )* ( \w+ .+ ) )

                  REPLACE \1$0
