Problem with multiple sheets in one XLS file

I have Excel with many sheets. When I create max. 240 pieces, it is ok, when there are more - Excel reports information that it is damaged - please help?

I solved the problem. The bull appears in Polish Excel when there is an Integer in the column and the value is above 999, then the sign 1,000 appears and in Poland this is the part after the decimal point, so Excel signals an error - I changed it to String.
