Number Formats Become Currency Formats in Japanese Excel
A report uses the Number data format and you
save it as Microsoft Excel
output. When you open the report in the Japanese version of Microsoft Excel, the data
format is listed as Currency rather than Number. This occurs because
Japanese Excel interprets the standard Number data format slightly
differently than other versions of Excel.
The value appears correctly in Number format. For example, if you specified five digits as your number format, five digits still appear. In Excel, click the Custom number format to see the exact format string being used.
