Searching Specific Excel Cell using Java Apache POI

I am using Apache POI API to read Excel file and check the quantity of products available or not. I am successfully reading excel file using below code but I am unable to read the specific cell (Quantity Column) to check weather asked product is available or not
package practice;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Iterator;
public class ReadingExcel {
private static String brand = "Nike";
private static String shoeName = "Roshe One";
private static String colour = "Black";
private static String size = "9.0";
private static String quantity;
public static void main(String [] args){
try {
FileInputStream excelFile = new FileInputStream(new File("C:\\Users\\admin\\Downloads\\Project\\assets\\Shoe_Store_Storeroom.xlsx"));
Workbook workbook = new XSSFWorkbook(excelFile);
Sheet datatypeSheet = workbook.getSheetAt(0);
DataFormatter dataFormatter = new DataFormatter();
Iterator<Row> iterator = datatypeSheet.iterator();
while (iterator.hasNext()) {
Row currentRow = iterator.next();
Iterator<Cell> cellIterator = currentRow.iterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
String cellValue = dataFormatter.formatCellValue(cell);
System.out.print(cellValue + "\t\t");
}
System.out.println();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
this is my excel file

using opencsv 4.1 i do this
import org.apache.commons.lang.StringUtils;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
...
try (InputStream excelFile = new FileInputStream(new File(fileName));
Workbook wb = new XSSFWorkbook(excelFile);) {
for (int numSheet = 0; numSheet < wb.getNumberOfSheets(); numSheet++) {
Sheet xssfSheet = wb.getSheetAt(numSheet);
xssfSheet.forEach(row -> {
Cell cell = row.getCell(0);
if (cell != null) {
if(StringUtils.isNumeric(cell.getStringCellValue())){
// Use here cell.getStringCellValue()
}
}
});
}
}

Use below for loop:
for(int r=sh.getFirstRowNum()+1; r<=sh.getLastRowNum(); r++){ //iterating through all the rows of excel
Row currentRow = sh.getRow(r); //get r'th row
Cell quantityCell = currentRow.getCell(4); //assuming your quantity cell will always be at position 4; if that is not the case check for the header value first
String currentCellValue = quantityCell.getStringCellValue();
if(currentCellValue.equalsIgnoreCase(<value you want to campare with>))
//<do your further actions here>
else
//do your further actions here
}

How to read and replace bookmark values with apache POI

i'm a complete novice with apache POI and i already tried several things. My problem is that i have a few bookmarks in a docx-File and i want to replace the value of them.
i already got so far that i add the text to the bookmark, but the previous value is still there
my code:
InputStream fis = new FileInputStream(fileName);
XWPFDocument document = new XWPFDocument(fis);
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs)
{
//Here you have your paragraph;
CTP ctp = paragraph.getCTP();
// Get all bookmarks and loop through them
List<CTBookmark> bookmarks = ctp.getBookmarkStartList();
for(CTBookmark bookmark : bookmarks)
{
if(bookmark.getName().equals("Firma1234"))
{
System.out.println(bookmark.getName());
XWPFRun run = paragraph.createRun();
run.setText(lcFirma);
ctp.getDomNode().insertBefore(run.getCTR().getDomNode(), bookmark.getDomNode());
}
}
}
OutputStream out = new FileOutputStream(output);
document.write(out);
document.close();
out.close();
the value of "lcFirma" is "Firma"
the value of the Bookmark is "Testmark"
my docx-File before:
Testmark -> name=Firma1234
my docx-File after:
FirmaTestmark
like i said the text is inserted before the value of the bookmark instead of replacing it, how do i replace the text instead?
Greetings,
Kevin

I also had similar requirement of setting the "Default text" field of a .docx bookmark. I was not able to do so, so, I did this as a workaround : Replaced the entire paragraph containing the bookmark with text. So, instead of the bookmark being populated with a default text, I had a paragraph that held the bookmarked text. In my case, the .docx had to finally converted to a .pdf file, so the absence of bookmark did not matter, but the presence of correct text was more important.
This is how I did it with Apache POI :

How I can export to excel a tree hierarchy using Apache POI?

I have a class:
class Node{
private Node parent;
private List<Node> children;
...
}
How I can export a tree of it's items to excel using Apache POI for getting document like this (I need to shift only first column in table):
A
B
C
D
E
F
G

A simple solution would be to create a NodeWriter class that essentially writes the Node onto an Excel Spreadsheet:
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class NodeWriter {
public void write(Node tree, String filePathName) {
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("Tree");
writeHelp(0, 1, tree, sheet);
try (FileOutputStream outputStream = new FileOutputStream(filePathName)) {
workbook.write(outputStream);
workbook.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private void writeHelp(int indent, int rowNum, Node tree, XSSFSheet sheet) {
if (sheet.getRow(rowNum) != null) {
writeHelp(indent, rowNum+1, tree, sheet);
} else {
Row row = sheet.createRow(rowNum);
Cell cell = row.createCell(indent);
cell.setCellValue(tree.getNodeName());
for (Node child : tree.getChildren()) {
writeHelp(indent + 1, rowNum + 1, child, sheet);
}
}
}
}
I've made some assumptions about your Node class. This solution ensures that you create a new Row and don't overwrite existing rows (as you would if that if loop wasn't there in writeHelp).

My solution - merging. Have a nice day. Thanks.
Looks like this:
https://docs.oracle.com/cd/E36352_01/epm.1112/disclosure_mgmt_admin/new_files/image002.jpg
My solution with merging:
private int createHierarchy(Sheet sheet, Node node, int currentRowIdx, int nodeLevel) {
if(node.getParent() == null){
sheet.setColumnWidth(8, 1000);
Row row = sheet.createRow(currentRowIdx);
row.createCell(nodeLevel).setCellValue(node.getName());
row.createCell(9).setCellValue(node.getValue());
sheet.addMergedRegion(new CellRangeAddress(currentRowIdx, currentRowIdx, nodeLevel, 8));
nodeLevel++;
}
for (Node node : node.getChildren()) {
Row row = sheet.createRow(++currentRowIdx);
row.createCell(nodeLevel).setCellValue(node.getName());
row.createCell(9).setCellValue(node.getValue());
sheet.addMergedRegion(new CellRangeAddress(currentRowIdx, currentRowIdx, nodeLevel, 8));
currentRowIdx = createHierarchy(sheet, node, currentRowIdx, nodeLevel+1);
}
return currentRowIdx;
}

Reading Excel checkbox values in Java Apache POI

I have spent countless hours trying to find a solution to this. I have tried Apache POI, JExcel and JXLS but no where have I found code to successfully read checkbox (form control) values.
If anyone has found a working solution then it would be great if you could share it here. Thanks!
UPDATE
I have written code that reads the checkbox but it cannot determine whether it is checked or not.

Sorry for the late reply, but I ran into the same. I found a trick to determine the checkbox state.
In your example you ar looping over the SubRecords and you examine the CommonObjectDataSubRecord. But the value for the checkbox can be found in the one of the SubRecord.UnknownSubRecord. This is unfortunately a private class so you cannot call any method on it, but the toString() reveals the data, and with a little regex the value can be found. So using the code below I managed to retrieve the state of the checkbox:
Pattern p = Pattern.compile("\\[sid=0x000A.+?\\[0(\\d),");
if (!(subRecord instanceof CommonObjectDataSubRecord)) {
Matcher m = p.matcher(subRecord.toString());
if (m.find()) {
String checkBit = m.group(1);
if (checkBit.length() == 1) {
boolean checked = "1".equals(checkBit);
checkBox.setChecked(checked);
}
}
}
Now my challenge is to retrieve the checkbox value in a xlsx file...
