RE: Writing to Excel corrupts the Excel file


I have a script that uses the data-driven framework using Apachi POI.  The file that I use is identical to the file in your tutorials (

My script is able to read from the Excel file without any problems, but writing to Excel is another matter.

I have the following code in my script:

for (int j = 1; j < 10; j++) {
boolean multiples = driver.findElements(By.xpath("//table[@id='Table4']/tbody/tr/td/table/tbody/tr[3]/td/table/tbody/tr[3]/td")).size()>0;
if (multiples == false) {
ExcelUtils.setCellData("Successful", j, 6);

}else {

ExcelUtils.setCellData("Multiple", j, 6);



If I remove the loop and just run the script once, the script runs successfully and the result is sent to the spreadsheet.  However, when I try to iterate the script with the for loop, it runs successfully for the first iteration, but in the second iteration, at the setCellData, the Excel spreadsheet is corrupted and the script then fails.

While trying to debug the issue I would watch the Excel file size (in Windows Explorer).  The file size before the test was run was 75kb.  After the first iteration the file size would drop to 62kb, after the second iteration the file size would drop to 0kb

I have had the same problem with trying to write to different cells in one row.

Does anyone know why Selenium corrupts Excel files, and how I can avoid it while still writing results to Excel?

Hi Simon,

Can you show us your excelutil.setdata method’s code. That may have some issue.
