问题 Apache POI 4.x here. I see there are two types of Workbook implementations: HSSF Workbook XSSF Workbook I need to write a Java 8 app that reads Excel sheets with either " .xls " (XLS) or " .xlsx " (XLSX) extensions. Meaning, Excel files that were saved in the "old" (pre 2003) format, or the newer one. Is it safe to assume I use HSSF for XLS files, and XSSF for XLSX files? Or is the mapping logic a little bit more complicated there? This answer seems to indicate I'm correct, but that doesn't

问题 I'm using Apache POI to alter an Excel file and put some data in it. Most of what I try goes well. However my currency formatting is not done 100% correctly... What I want is my currencies to be format like € 1.000,43 . So the Euro sign on the left, the amount on the right with dot as thousands separator, comma as the decimal separator and two decimals. If I do that in Excel and apply this custom formatting rule it works: "_ [$€-nl-BE] * #.##0,00_ ;_ [$€-nl-BE] * -#.##0,00_ ;_ [$€-nl-BE] * \"

问题 I am trying to rename headers of an existing xlsx-file. The idea is to have an excel-file to export data from XML to excel and reimport the XML once some user has made adjustments.
