NotOfficeXmlFileException: No valid entries or contents found, this is not a valid OOXML (Office Open XML) file - UNIT TEST Spring

I am trying to unit test this piece of code:
#Slf4j
#Service
#RequiredArgsConstructor
public class LeMigrationService {
private final MigrationServiceClient migrationServiceClient;
public FileUploadRs process(MultipartFile file) {
List<String> listOfCifs = null;
try {
listOfCifs = ExcelUtil.collectColumnByIndex(file, 0);
} catch (Exception e) {
LOGGER.error("Failed to load excel file content " + e);
}
return migrationServiceClient.process(listOfCifs);
}
}
The static method:
public class ExcelUtil {
public static List<String> collectColumnByIndex(MultipartFile file, int index) throws Exception {
List<String> listOfCifs = new ArrayList<>();
Workbook workbook = new XSSFWorkbook(file.getInputStream());
Sheet sheet = workbook.getSheetAt(0);
for (Row row : sheet) {
Cell cell = row.getCell(index);
int cellLength = cell.getStringCellValue().length();
if (cellLength < 9) {
StringBuilder str = new StringBuilder();
for (int i = 0; i < 9 - cellLength; i++) {
str.append("0");
}
str.append(cell.getStringCellValue());
listOfCifs.add(str.toString());
}
if (cellLength > 9) {
break;
}
if(cellLength == 9) {
listOfCifs.add(cell.getStringCellValue());
}
}
return listOfCifs;
}
}
And finally my unit test:
#RunWith(MockitoJUnitRunner.class)
public class LeMigrationServiceTest {
#Test
public void processFile_FileContentIsOk() throws Exception{
//arrange
final MockMultipartFile fakeFile = new MockMultipartFile("file", "file.xls", MediaType.TEXT_PLAIN_VALUE, "0123456789".getBytes());
//act
final List<String> actual = ExcelUtil.collectColumnByIndex(fakeFile, 0);
final List<String> expected = new ArrayList<>();
expected.set(0, "0123456789");
//assert
assertThat(actual).isEqualTo(expected);
}
}
When I run the test, I get the error when it calls the static method "collectColumnByIndex". Apparently I do not create well the object "Workbook" inside the method "collectColumnByIndex". Do you have any ideas of how to solve this?

I want to write the ouput of displayDirectoryContents to a excel sheet

I want to write the output of the displayDirectoryContents to a excel sheet
I have tried using the Apache POI method I want to get the output to a excel sheet
Folder and filename in one column and
the name of the files in another column
import statements

excelData[0][1] = message;
myRow = mySheet.createRow(rowNum);
for (int cellNum = 0; cellNum < 2; cellNum++) {
myCell = myRow.createCell(cellNum);
myCell.setCellValue(excelData[0][cellNum]);
}
try {
FileOutputStream out = new FileOutputStream(dest);
myWorkBook.write(out);
out.close();
} catch (Exception e) {
e.printStackTrace();

I want two columns in an excel sheet with column 1 containing File or
Folder and column 2 containing the name of the file/folder
eg
File books.xml
Folder Script
Thus i want to write the output to the excel sheet
i am using the function excel log to write to the output screen

I use this to write to an excel - however I make it .csv format, not xls. Therefore this might not be what you need, but it's still partially useful as it's writing in a file that can be opened by excel efortlessly.
public static void printAtFile(String filename, String header, String content[])
{
filename+=".csv";
System.out.println("Start creating file "+filename);
PrintWriter writer = null;
try {
writer = new PrintWriter(filename);
writer.println(header);
for(String u:content)
writer.println(u);
writer.close();
} catch (Exception ex) {
System.out.println("Error while writing at file "+filename);
}
}

I'm getting errors at getField, addField methods of Row interface. First thing, is it correct declaration? private static Row row =new Row();
Row is from org.apache.poi.ss.usermodel.Row;

You can use the famous Apache POI for creating excel files. It is available here with documentation links. Your question is very general. You should try to do it on your own and get back to stackoverflow when you have a precise programming question.

Your problem can be broken down into the following 3 parts
Parse the JSON
Read the required values
Write the data in excel
For the first part you can use the any of the wide range of JSON parsing APIs and can also refer to this question
For the second part, once you get the data into your code, you need to be able to read through it, for this you'd need to be able to traverse through the Object that you'll get by using the above mentioned API.
And for the last part, you can simply write the output on a file in CSV format and open it in Excel.
This answer may seem vague, please comment if you need clarification

Unable to insert values into existing work book [apache poi]

I would like to insert values into existing work book. Here the class that encapsulates this logic:
public class FormulaExtractor {
private String pathToExcelFile;
private XSSFWorkbook workbook;
private Map<Double, Formula> idFormular = new HashMap<>();
public FormulaExtractor(String pathToExcelFile) {
this.pathToExcelFile = pathToExcelFile;
try (FileInputStream fileInputStream = new FileInputStream(new File(pathToExcelFile))) {
this.workbook = new XSSFWorkbook(fileInputStream);
} catch (FileNotFoundException e) {
System.out.println("Cannot locate a xls file. Exception: " + e.toString());
} catch (IOException e) {
System.out.println("IO exception " + e.toString());
}
}
public void insertHumanReadableFormulas() throws IOException {
XSSFSheet sheet = workbook.getSheetAt(0);
Iterator<Row> rowIterator = sheet.iterator();
while (rowIterator.hasNext()) {
Row currentRow = rowIterator.next();
Cell cell = currentRow.createCell(CellReference.convertColStringToIndex("K"));
cell.setCellValue("Some dummy variable to test. ");
}
FileOutputStream fileOut = new FileOutputStream(new File(this.pathToExcelFile));
workbook.write(fileOut);
fileOut.close();
}
}
How do I use it:
public class App {
public static void main(String[] args) throws IOException {
final String pathToExcel = "some/path/some_excel.xlsx";
FormulaExtractor formulaExtractor = new FormulaExtractor(pathToExcel);
formulaExtractor.insertHumanReadableFormulas();
}
}
I don't get any exception or error. When I open my excel file, I simply cannot find values in a column "K". What am I doing wrong?
