Dear sir,
I'm excited about your project, because I've really rich experience in the same profile.
I've developed many projects similar to yours and excellent skills.
If you award me, I'll provide wonderful result on time.
I have two solution for this problem. Which are as follows.
1. We should upload these files into database without reading the file. ("because reading unstructured data could be very complex").
2. We can use OCR and ML algorithms for extraction But, I am concerned about accuracy.
Your further response will be greatly welcome.
Regards,
Vishal Sharma
