Notepad++ regex / Excel macro to delete specific range of lines

Question

I have data like follows:

1. gooddata
2. gooddata
3. gooddata

FF

randomdata

irrelevantdata

---

headers

---

4. gooddata

5. gooddata

6. gooddata

FF

and it goes on repeatedly for over thousands of lines. I have two proposed solution ideas

Notepad++

Create a regex to Find x criteria and delete subsequent of y number of lines

or

VBA

Find "FF" and delete everything until "---". find next "FF" and delete everything until next "---" .

So the output intended be like:

1. gooddata
2. gooddata
3. gooddata
4. gooddata
5. gooddata
6. gooddata

Thanks for your help.
