Let's see if I understand you correctly.
You have a huge task that involves data entry.
You would like to be able to type the data with errors.
You want a software program that would detect the errors and automatically correct them.
If my interpretation is incorrect, then please clarify what you mean.
If my interpretation is correct please let us know. There is to my knowledge NO program that can do this with perfect accuracy. That is because the computer has no way of knowing what is on the hard-copy, and it cannot think or consider context. I have heard
that there are programs that are quite a bit better than MS-Word with prose-type
text, but they are not perfect. However, I also heard that said programs are hideously expensive. I do not know the names of them.
The best way of producing error-free text or data is to type it error-free in the first place. Also, go back and proof-read for errors, but go backward word-by-word to defeat the prediction process of the brain that causes one to overlook typos. Of course, this fails if you right
the wrong word instead of the write
word. (misspellings intentional).
So, go forward again to see if you have written words that were not the intended words.
