Hi, @jinko-solar, @alan-kilborn,@meta-chuh, @peterjones and All,
Aaaaaaaaah I see ! Just the way to interpret the OP’s request !
So, Alan, rest assured, your regex S/R is working as expected !
Assumming the text :
0300 8229386
0300 8253137
0334 0210214
0300 2692165
03008229386
03008253137
03340210214
03002692165
The regex S/R, below :
SEARCH ((^\d+.+\R){4})\R OR ^((\d+.+\R){4})\R
REPLACE \1
will leave you with the text :
0300 8229386
0300 8253137
0334 0210214
0300 2692165
03008229386
03008253137
03340210214
03002692165
