View Replies View RelatedValue Format While Reading Excel Data Into Java
Jan 20, 2015I am reading Excel data using java apache. I got format issue while reading double value such as 869.87929 (in excel) into 869.8792899999999 (in java).
I'm using following files to read excel data.
1. Schema.csv: SheetName,2-int-Double
2. File.xls:
col1 | col2
123 | 869.87929
Sample code:
if(type.equals("Double")){
String str = content[i-1];
//System.out.println(str);
BigDecimal d = new BigDecimal(str);
listObjects.add(d);
}
Note: type from schema.csv & content [] value from file.xls
If I print **str**, it shows value as 869.8792899999999.
But i need to get **str** value as 869.87929. How can I get it?

JSP :: Download Data In Different Sheets In Excel
May 27, 2010I have a requirement to download the data from DB to CSV/Excel. What I did is retrieving all the records from DB and store in the List and pass that list to the jsp page. In JSP page, I am using the below setting to download it to CSV/EXCEL.
response.setContentType("application/vnd.ms-excel");
String fileName = "Report"+System.currentTimeMillis()+".xls";
response.setHeader("Content-disposition","attachment;filename="+fileName);
It was working fine. But I have an issues in it. Excel is capable of storing it only 65,536 rows. Even all the data getting downloaded to CSV/excel (> 65,536), while saving I am getting error from excel saying that it can't save more than 65,536 rows and the below data won't be saved.
This workbook contains data in cells outside of the row and column limit of the selected file format.
Data beyond 256 (IV) columns by 65,536 rows will not be saved.
Formula references to data in this region will return a #REF! error.
I am not opt for POI apache third party at this point of time. Is it possible to download it in other sheets if it exceeds the max limit.
Example: Having data of around 100,000.
Download 65,536 - Sheet 1
Remaining in Sheet 2,3.. of the same excel.

Write A Java Program To Fill Excel Spreadsheet
Jul 15, 2014I have an excel spreadsheet, with a specific filename and location which doesn't change (e.g. C:/workbook.xls)What I would like to do is have a window open when I open an .exe file, and in this window is a bunch of check boxes, text areas and drop down boxes (I can implement these, that's about my level of JAVA)
Then, when I click on a button in this window (for example, a button which says "Save"), the data from all these boxes and menus etc. goes into specific cells in the excel spreadsheet. Or if certain values are selected from a drop down menu, then a bunch of cells are empty.
