Hello,

I've got some huge text files look like below. I've cut a couple blocks from about 67000 blocks in the file. Basically, I would like to pick up the second line of each blocks.

Code:
Grid-ref=   1, 148
 3020 2820 3040 2880 1740 1360  980  990 1410 1770 2580 2630

 3928 2964 3049  807 1030  131 1259  366  958 3300 1331 1939

So after manipulating the file, it seems to be like this.

Code:
Grid-ref=   1, 148
 3020 2820 3040 2880 1740 1360  980  990 1410 1770 2580 2630
Grid-ref= 217, 158
 4582 2779 2745 1286 1131  409 1834 2733  961 1305 1798 2571
Grid-ref= 217, 159
 4170 3020 2930 1225 1221  615 1711 2395 1002 1544 1743 2356

I've no clue how to work with a huge text file like this and Excel over Window definitely doesn't work.

Any idea would be much appreciate.

Best wishes,
