I use Apache POI to change some values in cells in an Excel workbook. This workbook has integrated formulas in some cells. These formulas use values from cells where I change the value. But I don’t see any difference either in Apache POI or after saving in a file. I tried next actions:

I am trying to use an excel to write the into new file using Apache POI. This is the method code,

I am generating an .xlsx file using Apache POI 5.2.5, sending the byte array to the client side and downloading the file locally on the client’s machine.

Have used SXSSFWorkbook in excel file creation & downloading after clicking a button. Below is the java code snippet.

I am using apache poi 3.11. When initializing the workbook of an excel file .xlsm containing comments, the error “org.apache.xmlBeans.xmlException: error: Subsequent sections cannot have content.”

I am using the Apache POI library 5.2.5 to read an excel xlsx file into a Map and then read that data in a second operation. The problem I am having is that the code I am using will not recognize that a cell is blank or null and skips, does not preserve the organization or order of the source sheet. At the point where I need to work with the Map and access it by index, the indices are off in rows where there are blank cells. This is especially true where a row starts with an empty or blank cell and the assembly of the Map is then off by 1, resulting in an error as the expected value is shifted. The code I am using is borrowed from Baeldung here: https://www.baeldung.com/java-microsoft-excel, with a couple edits/additions to try to force a read and assignment of the blank or empty cells. These edits include a call to policy workbook.setMissingCellPolicy(Row.MissingCellPolicy.RETURN_BLANK_AS_NULL); and an if statement at the beginning of the loop to handle cells if (cell == null) { data.get(i).add(" "); continue; } I have spent quite a while debugging the code to find out exactly where the cells are being checked for null, empty or blank and then skipped in order to implement an effective fix but have not been able to find it. Any help is greatly appreciated. Here is the code in entirety: `public Map<Integer, List> readExcel(String fileLocation) throws IOException {
