I’m afraid that, in order to use the column mode, in a reliable way, we should align the comma symbols, padding preceding positions with spaces chars !

So, this time, the regex solution seems to be more secure ;-))

For instance, with that sample text, below :

#,6100795442608787,1
#,205300099864,1
#,65433455333,5
#,20530002200815618844,1
#,3360,20
#,718103267854,2
#,67764334775,8

Here is a regex S/R which deletes any non-null range of digits, after the 11th, till the second comma of each line :

• SEARCH ^#,\d{11}\K\d+(?=,)

• REPLACE Leave EMPTY

• Tick the Wrap around

• Select the Regular expression search mode

• Click, exclusively, on the Replace All button

And, we would obtain the expected result :

#,61007954426,1
#,20530009986,1
#,65433455333,5
#,20530002200,1
#,3360,20
#,71810326785,2
#,67764334775,8

I made the assumption that the OP may have other lines (that are longer) intermingled with the ones shown that he doesn’t want affected. Otherwise, yes, you are right, this is a good application of column mode editing, perhaps in combination with the Begin/End Select command, which also works with column mode editing, although it is a bit obscure (you have to get into column mode as you are positioning the caret for the “end select”).

Perfect thank you very much.

You might try:

Find: ^(#,\d{11})\d(?=,)
Replace: \1
Search mode: Regular expression
