but when it is scraped result is +1500.
Here issue is 4 is read as +1.

Can anyone help me to map if result is +1 than it should change to 4.
How can i over come this issue with out any API’s.

Thanks in advance.

Can you send your pdf?

new1.pdf (31.3 KB)

You can use the ABByy Ocr activity to extract the data from the pdf and then apply the regex on it.

any suggestion without any API.
