Use Regular Expression (REGEX)
- Open Find (CTRL+F)
- Make sure within the "Search Mode", the "Regular expression" is checked [o]
- Paste the below line in "FIND" box
^([^\t]+)\t([^\t]+)\t([^\t]+)\t([^\t]+)\t([^\t]+)\t([^\t]+)\r\n^([^\t]+)\t([^\t]+)\t([^\t]+)\t([^\t]+)\t([^\t]+)\t([^\t]+)\r\n\r\n
- Paste the below line in "REPLACE" box
$1: $7\r\n$2: $8\r\n$3: $9\r\n$4: $10\r\n$5: $11\r\n$6: $12\r\n \r\n
^ = From the start of line
([^\t]+) = All those which are not a TAB char.
\t = Followed by a TAB char.
\r\n = New Line / Linefeed / End of line char
$1,$2....= Refers to the position of ([^\t]+) in the FIND
NOTE: I added extra \r\n\r\n
at the end of REPLACE as I thought you might want to separate multiple sets of records.
