Converter of prices from different suppliers into a single forma

The task from the Customer:
To put in order the prices from different suppliers so that they could be uploaded to the Prom website in the future without errors and with all the data.

Implementation.
* Desktop application for Windows
* The list of all prices is already in the programme in the Combobox field.
* Two modes of operation:
- Parsing prices - updates prices and creates a file when downloading which, simply updates prices and availability
- Full parsing - search for products that are not available on the main site. Creation of a file ready for uploading to the site with all the characteristics.

The programme shows the progress of the work (progressbar).
