File processing and translation into Polish

File processing and translation into Polish. You need to compare two files in the Excel format - old and new edition (total 70 pages) - and remove from the new version all the exact repeated lines, so that they remain only modified or added. The resulting set of lines must be translated into the Polish language, with the formatting. The result will be presented in two files.
