在使用JasperReports导出为Excel格式的过程中如何避免'BIFF8的允许列范围为（0..255）或（'A'..'IV'）'错误

Question

During export report as Excel sheet via JRXlsExporter I got the error: Invalid column index (256). Allowable column range for BIFF8 is (0..255) or ('A'..'IV') Invalid column index (256). Allowable column range for BIFF8 is (0..255) or ('A'..'IV') . How to fix this issue?

Answer 1

JasperReports is using Apache POI library for exporting reports to MS Excel format.

The engine has several exporters for proceeding export to MS Excel format:

• JRXlsExporter - generates output as xls file
• JRXlsxExporter - generates output as xlsx file

The old versions of MS Excel have limitation of using less than 257 columns at workbook. The new versions (2007+) have the new limitation: 16 384 columns.

The JRXlsxExporter uses the API (based on XSSF ) that allow to export report in a new format ( .xlsx ). The JRXlsExporter is using HSSF implementation of Apache POI .

To avoid this error it is enough to use JRXlsxExporter .
