Using OpenXml on a excel sheet i create new worksheet.
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
Sheet sheet = new Sheet()
{ Id = relationshipId, SheetId = sheetId, Name = sheetName };
workBookSheets.Append(sheet);
How do i move this newly created worksheet in the place of a another worksheet ?
For example :There are three worksheets
A,B,C and i create a new worksheet A1 and want A1 to be in the place of B . How do i go about this ?
Thanks
I believe you can do something like this:
document.WorkbookPart.Workbook.Sheets.InsertBefore(sheet, sheetB);
Where "sheetB" would be the OpenXMLElement. So rather than appending the sheet to the workbook you would insert sheet A1 before sheet B.
I was able to make a sheet the first in the workbook by doing the following:
document.WorkbookPart.Workbook.Sheets.InsertBefore(sheet,
document.WorkbookPart.Workbook.Sheets.FirstChild);

I have the following error...
System.Data.DuplicateNameException: 'A column named 'samplex' already
belongs to this DataTable.'
I have large multiple excel files that need merging into one. But all the column names are the same. So I think that is why I am getting this error.
All the data is in sheet1 one from each excel files. Searching on the net the best one I found was using Spire.Xls, sample taken from here
My code sample, using console...
using Spire.Xls;
::
::
Workbook workbook = new Workbook();
workbook.LoadFromFile(#"filea.xlsx");
Workbook workbook2 = new Workbook();
workbook2.LoadFromFile(#"fileb.xlsx");
Workbook workbook3 = new Workbook();
workbook3.LoadFromFile(#"filec.xlsx");
Worksheet sheet2 = workbook3.Worksheets[0];
DataTable dataTable = sheet2.ExportDataTable();
Worksheet sheet1 = workbook.Worksheets[0];
sheet1.InsertDataTable(dataTable, false, sheet1.LastRow + 1, 1);
//save the workbook
workbook.SaveToFile("result.xlsx");
Appreciate if anyone can help me on this?
Since you're able to get DataTable objects and all the column names are the same, I'd bet you could use DataTable.Merge() -
Workbook workbook1 = ...;
Workbook workbook2 = ...;
DataTable bookTable1 = workbook1.ExportDataTable();
DataTable booktable2 = workbook2.ExportDataTable();
bookTable1.Merge(bookTable2);
// Spire specific API calls to save bookTable1 to Excel file
The only requirement for your data is that you have a key column. To configure the DataTable with a key -
bookTable1.PrimaryKey = bookTable1.Columns("DataID" /* your key column name here */);
When I used Microsoft.Office.Interop.Excel, sample taken from here, it solve the problem regarding columns with same name. The code is long and complicated but it works but you will need Microsoft Office on the machine. Only a slight problem is that the results shows in new sheet, it doesn't go directly into sheet1. If anyone can advise me on this, it will be ideal.
I am using Visual Studio 2017.
You can use CellRange.Copy(CellRange destRange) method in Spire.XLS to merge worksheets from different workbooks into one, it won't throw the DuplicateNameException.
Refer to the following code:
//Load the first workbook
Workbook workbook1 = new Workbook();
workbook1.LoadFromFile("Sample.xlsx");
Worksheet sheet1 = workbook1.Worksheets[0];
//Load the second workbook
Workbook workbook2 = new Workbook();
workbook2.LoadFromFile("sample2.xlsx");
Worksheet sheet2 = workbook2.Worksheets[0];
int a = sheet2.LastRow;
int b = sheet2.LastColumn;
//Copy data from the 2nd row in sheet2 into sheet1
sheet2.Range[2, 1, a, b].Copy(sheet1.Range[sheet1.LastRow + 1, 1, a + sheet1.LastRow, b]);
workbook1.SaveToFile("reslut.xlsx", ExcelVersion.Version2013);
I have already tried the code and it works well on my side.
I've got an Excel workbook, and needed to read data from the third (and final) worksheet in that workbook. I used old code that scanned through all worksheets, but modified it to jump to the third worksheet:
foreach (var worksheet in Workbook.Worksheets(excelInput).skip(2))
This took me to the third worksheet, my code would execute, and everything was fine.
Now, the client is sending either a three-tabbed Workbook with the sheet I need elsewhere (either 1st or 2nd tab), or they're sending a four-tabbed Workbook, and the sheet I need could be anywhere.
Is there a way to choose the one-and-only sheet that I need by either finding the name of the tab, or the text in cell A1, and using that worksheet and that worksheet only?
Thanks very much in advance!
If you do not know “where” the worksheet is located in the workbook, you can loop through each sheet and check either the sheet name, or as you say “text in cellA1”.
Checking the text in cell A1… I am not sure how you would know if the sheet was the proper one by looking at the first cell. What if all sheets have a value in the first cell? And what would that cell contain? Would the cell contain text that says “this is the correct sheet”? So I am assuming that this workbook only has one sheet with data, and the other sheets are empty.
Looping through the sheets in the workbook is relatively easy, however if you do not know what the name of the sheet is, then it may be difficult to identify the proper sheet. Using my assumption (above) of only one sheet with data, then you can check each sheet to see how many rows of data each sheet has. Then the one with more than 1 row of data is the sheet you are looking for. If the other sheets have data also, then this won’t work and you are going to have to identify the target sheet some other way.
If you DO KNOW the name of the worksheet, then you are good to go. In your case you stated that the worksheet was “Sheet3” but may not be in the 3rd index of the worksheets in the workbook. In this case you can reference the sheet by name as you asked with:
Worksheet target = workbook.Sheets[“Sheet3”];
If target returns null, then the worksheet named “Sheet3” does not exist. If target is not null, then you have found the worksheet and it can be referenced by the target Worksheet variable.
From what you described, if the sheet is always named ”Sheet3” then simply use:
if (SheetExist(workbook, "Sheet3"))
{
Worksheet myWS = workbook.Sheets["Sheet3"];
if (myWS.Cells[1,1].Value != null)
Console.WriteLine("\nCell[1,1] of sheet3: " + myWS.Cells[1, 1].Value.ToString() + "\n");
else
Console.WriteLine("\nCell[1,1] of sheet3 is Null/has no value");
}
else
{
//Console.WriteLine("Worksheet NOT found!");
// sheet named "Sheet3" does not exist in the workbook
}
Below is a method that you can use to see if a "worksheet" with the supplied name “sheetName” exist in the given ”workbook.” If you need the index of the worksheet you could change this to return the index or -1 if it does not exist.
private static bool SheetExist(Excel.Workbook workbook, string sheetName)
{
Worksheet target = workbook.Sheets[sheetName];
if (target != null)
{
//Console.WriteLine("Worksheet found!");
return true;
}
else
{
//Console.WriteLine("Worksheet NOT found!");
return false;
}
A method that loops through all the sheets and checks the number of rows with data using the “UsedRange” function. This also identifies the index of the worksheet in the workbook.
private static void LoopThruAllSheets(Workbook workbook)
{
Sheets allWorkSheets = workbook.Worksheets;
foreach (Worksheet curWS in allWorkSheets)
{
Console.WriteLine("Worksheet : at index " + curWS.Index + " name: " + curWS.Name.ToString() + " UsedRange.Rows.Count: " + curWS.UsedRange.Rows.Count.ToString());
}
}
Hope this helps
How can i copy one worksheet values and paste an another worksheet on within a workbook in aspose.cell using asp.net with c#?
Thanks and regard,
Parthiban K.
I work as Social Media developer at Aspose. Aspose.Cells offer multiple options to achieve your desired results. You can Export the data from one worksheet to another and then import the data to the destination worksheet using . You can also copy all the data as range to the destination worksheet. Check the following samples:
Copy the Range from First Worksheet to destination worksheet
//Open the workbook
Workbook workbook = new Workbook("book1.xlsx");
//Select source worksheet
Worksheet worksheet = workbook.Worksheets[0];
//Select Destination Worksheet
Worksheet destSheet = workbook.Worksheets[1];
//Get the range of cells with all the data from source worksheet
Aspose.Cells.Range sourceRange = worksheet.Cells.MaxDisplayRange;
//Create a range with same row and column count as source worksheet
Aspose.Cells.Range destRange = destSheet.Cells.CreateRange(sourceRange.FirstRow, sourceRange.FirstColumn, sourceRange.RowCount, sourceRange.ColumnCount);
//Select Paste Options
PasteOptions options = new PasteOptions();
options.PasteType = PasteType.All;
//Copy the range from source worksheet to destination.
destRange.Copy(sourceRange, options);
//Save the updated worksheet
workbook.Save("book1.xlsx");
Export data from one worksheet and import to another
//Open the workbook
Workbook workbook = new Workbook("book1.xlsx");
//Select source worksheet
Worksheet worksheet = workbook.Worksheets[0];
//Exporting the of worksheet to DataTable
DataTable dataTable = worksheet.Cells.ExportDataTableAsString(0, 0, worksheet.Cells.MaxRow, worksheet.Cells.MaxColumn, true);
//Select Destination Worksheet
Worksheet destSheet = workbook.Worksheets[1];
//Import data to destination worksheet
destSheet.Cells.ImportDataTable(dataTable, true, "A1");
//Save the updated worksheet
workbook.Save("book1.xlsx");
I am creating an application to retrieve the column names into listbox from a particular excel sheet and match the column names with the database columns and insert it into the excel data into table
Can you explain how can I can do it?
Already I have retrieved sheet names into the list box
Microsoft.Office.Interop.Excel.Application app = new ApplicationClass();
Workbook workBook = app.Workbooks.Open(#"your_file_path");
Worksheet workSheet = (Worksheet)workBook.Worksheets.get_Item(1);
Range range = workSheet.UsedRange;
for (int i = 1; i <= range.Columns.Count; i++)
{
ListBox3.Items.Add(((Excel.Range)range.Cells[2, i]).Value2);
}

I'm trying to read data from a multiple sheet excel file.
The first sheet has column headers. the second sheet does not. and the third one does not have any. I can successfully read from the first sheet.
When i try reading from the sheet without header, the program throughs an exception.
var sheet1_data = from c in excel.Worksheet<Species>("Sheet1") select c; // This works and the question is how do i retreive data from sheet2?
I'm currently using this:
var Sheet2_data = from b in excel.WorksheetNoHeader("sheet2") select b;
When i try and read from sheet2_data, i get the following exception:
'sheet2' is not a valid worksheet name. Valid worksheet names are: 'sheet2,sheet3',
Any help will be highly appreciated.
B.
the sheet name can be abstract using GetWorksheetNames() method.
var sheets = excel.GetWorksheetNames();
foreach(var sheet in sheets)
{
var sheetData = from x in excel.Worksheet(sheet) select x;
}
