Sir,
Here is the File. How will I extract the Required Text at many instances and need to replace it with my Required Text.
https://www.dropbox.com/s/p2ud6aknblqwxw3/123Data.txt?dl=0

I am not able to get how I will Use STREXTRACT() for extracting String at Multiple places and Replace it, Else I am infact more comfortable with STREXTRACT()

Thanks
