Your tool that analyses different CVs in all document types and transform them into an excel sheet can be built.
BUT, guaranteeing no fault in the results depend on the quality of these CVs:
Are all informations needed in the final Excel sheet written in the CV?
Is the CV Clear (Delivered as an electronic document or a scanned image?
Does the CVs have headings (Example: First Name: John, Last Name: Smith...)?
If the CV is delivered as an electronic document (MS Word, Excel, PDF), error-free results can be guaranteed.
If CVs elements does not have headings, I will use last names databases to distinguish between First and Last names, I will use Data formats to get every information from the CV: Addresses and telephones Formats, companies and universities lists...
The bottom Line, Your Tool can be made and I can add as many options to it as your budget allows.
Please send me some sample CVs so I can make a demo application for you.
