Is there a way to parse heterogeneous price lists?

Question

Parsing

Nothing comes to mind.
There are pages. There are different formats for displaying prices.
It seems to me that any script will make too many mistakes, which in the end is easier to do by hand.

Answer 1

I'll say something like this, but it might help.
Somehow there was a similar task, we used Price Importer .
As analyzed, they gave their own archives and received parsing in Excel and other formats. Well, then we did what we needed.
Paid solution, really.
I don't know how applicable this is to your tasks.

Answer 2

If there are a lot of names in the price list, it's easier to write scripts, even if they are rigidly tied to certain sheets in Excel. Unfortunately, there is no silver bullet, yes.

Answer 3

dig towards algorithms from Data Mining

Answer 4
