and this will be the ending point

I want to remove all the rest of the string. Just to keep the strings between the two desired blocks
The expected output would be

In brief to include the starting point but not to include the ending point
then export the string to another text file in the same path

Thanks advanced for help

Thanks a lot.
In fact this is simple example but the original file has a lot of quotation marks .. Sorry for confusion
What I want to focus on is the strings of start and end .. the quotation is just part of the string

Thanks a lot Mr. Jindon
The desired output is in post #1
In this output there may be a lot of " (quotation marks)

I don't see you use the starting and ending strings. Those would be as blocks for the desired part
Please provide me with the whole code as I am confused

This is a working code for the sample provided ..

But how can I define starting point (as string) >> "start point" and also define ending point (as strng) >> "Dead line"
I need to define those strings (both the start and the end) in the code itself

This gives me red color which refers to error ..

May be easy for you
I tried your suggestion and I got 'Invalid procedure or call'

Is that right?

That's my bad. In the text file the string is "Deal line" not "Dead line" ....
How can in this case (case of not finding the ending point string) >> to skip the ending point and take the rest of the text file?

Thanks a lot Mr. Jindon and thanks a lot for your patience
I have fixed that last point

Trying to see the code on original code I found that the starting point doesn't deal with the second occurrence of the string but it deals with the last occurrence of it

I just need to deal with the second instance of this string "start point" ..

Try this sample please
