2. If you convert pdf into excel, I recommend a software, ABBYYFineReader. It can be said that this software is the best recognition software in the world at present. It can convert pdf documents into word or excel, but you still need to proofread them. After all, we must ensure the accuracy, but if we control the accuracy when scanning, it will save a lot of things.
PS: Now many softwares on the market say that pdf or pictures can be converted into word or excel. In fact, that's a bluff, because the word they converted can't be edited. In essence, it is to post pictures in the word, which is disgusting. But what ABBYYFineReader transforms is editable.
