I have excel template with empty one-column table. I need to populate it with some string values (this is needed for setting lookups using data validation, but I guess it doesn't really matter)
I came up to getting Table object and I assume I should use Append method
var workBookPart = doc.WorkbookPart;
var lookupsSheet = (Sheet)workBookPart.Workbook.Sheets.FirstOrDefault(x => (x is Sheet && ((Sheet)x).Name == "Lookups"));
var worksheetPart = (WorksheetPart)workBookPart.GetPartById(lookupsSheet.Id);
var table = worksheetPart.TableDefinitionParts.FirstOrDefault(x => x.Table.DisplayName == "ValuesTable")?.Table;
Can someone enlighten about the correct way of adding rows to such table. Thanks!
I would suggest you use the ClosedXML library to set the values of cells in your worksheet. By using ClosedXML, you will be able to populate the cells you want in the following fashion:
var workbook = new XLWorkbook();
var ws = workbook.Worksheets.Add("Demo");
// Set the values for the cells
ws.Cell(1, 1).Value = "Value";
ws.Cell(2, 1).Value = 1;
ws.Cell(3, 1).Value = 2;
ws.Cell(4, 1).Value = 3;
ws.Cell(5, 1).Value = true;
Note that you can set the value of a cell to a string, an integer, and a boolean without doing any explicit casting. You can set the value of a cell without doing any explicit casting to other types as well, as it is explained in the following link: Cell Values.
For more information regarding the ClosedXML library please refer to the documentation.
As a side note, I was really eager to use Open XML to manipulate Excel spreadsheets but I found ClosedXML way easier to use.

In C# I have populated an excel file with data. Now I would like to create a table starting at cell A2.
I am using the code below to create the table but instead of creating the table starting at Cell A2, the table is being created starting at cell A3
using var package = new ExcelPackage(file);
var ws = package.Workbook.Worksheets.Add(Name: "MainReport");
var range = ws.Cells[Address: "A2"].LoadFromCollection(people, PrintHeaders: true);
range.AutoFitColumns();
//Formats Header row
ws.Cells[Address: "A1"].Value = "My Data!";
ws.Cells[Address: "A1:C1"].Merge = true;
ws.Column(col: 1).Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
ws.Row(row: 1).Style.Font.Size = 24;
ws.Row(row: 1).Style.Font.Color.SetColor(Color.Pink);
ws.Row(row: 2).Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
ws.Row(row: 2).Style.Font.Bold = true;
ws.Column(col: 3).Width = 20;
//create a range for the table
ExcelRange range_table = ws.Cells[2, 1, ws.Dimension.End.Row, ws.Dimension.End.Column];
//add a table to the range
ExcelTable tab = ws.Tables.Add(range_table, "Table1");
//format the table
tab.TableStyle = TableStyles.Medium2;
Excel itself works so that if you select A2:C4 and create a table and you say "has no Headers" it will put some generic headers in A2:C2 and shift the data area (and the data if there is any) to A2:C5.
If you say "has Headers" the headers will be defined in A2:C2, too, but the data only is in A3:C4.
The real Excel obviously does some guessing whether headers are present or not and pre-ticks the box for you.
As stated here in the API Documentation, there is no flag to define if headers are present in the range so there might be no guessing and it might be assumed it is "no" and the shifting as explained on top takes place.
If you take that into consideration you should be able to work it out.
I have a vsto application that populates an Excel sheet.
First I populate the datatable. The next function is to create a vsto listobject:
// Populate the sheet
XlsInterop.Excel.Worksheet worksheet = (XlsInterop.Excel.Worksheet)Globals.ThisAddIn.Application.ActiveWorkbook.Worksheets.Add();
extendedWorksheet = Globals.Factory.GetVstoObject(worksheet);
XlsInterop.Excel.Range cell = extendedWorksheet.Range["A1"];
excelItemsList = extendedWorksheet.Controls.AddListObject(cell, sheetName);
excelItemsList.AutoSetDataBoundColumnHeaders = true;
excelItemsList.DataSource = dt;
excelItemsList.ListColumns[5].Range.NumberFormat = "#";
Now the problem is that in column "5" I have values like 005, 004. In Excel, the values display as 5 and 4. How can I make sure that the values in Excel show the same values as in my database?
If I change my code like:
excelItemsList.SetDataBinding(dt);
excelItemsList.ListColumns[5].Range.NumberFormat = "#";
excelItemsList.SetDataBinding(dt);
It is doing what I want, but I don't think that this is the way to go.
If you know how many leading zeros you need, you can then format the column with that.
.NumberFormat = "000";
The column would then still be evaluated as a number.
I am writing an application in which I need to store data cell values into excel sheet. Everything is working fine but the problem is everytime I run the application, it overwrites the existing data.
So far the code I have taken from Github:
var workbook = new XLWorkbook();
var worksheet = workbook.Worksheets.Add("Sample Sheet");
worksheet.Cell("A1").Value = this.textBox1.Text;
worksheet.Cell("B1").Value = this.textBox2.Text;
worksheet.Cell("C1").Value = this.textBox3.Text;
worksheet.Cell("D1").Value = col1;
worksheet.Cell("E1").Value = col2;
worksheet.Cell("F1").Value = this.textBox6.Text;
workbook.SaveAs("HelloWorld.xlsx");
Note: I don't want to save data using datatable or anything. I just want to get values from textboxes and append them to the existing sheet. I have visited many stackoverflow post but they doesn't helped me much.
Thanks in advance!
Hope this helps:
var wb = new XLWorkbook("Path to file");
IXLWorksheet Worksheet = wb.Worksheet("Tab name");
int NumberOfLastRow = Worksheet.LastRowUsed().RowNumber();
IXLCell CellForNewData = Worksheet.Cell(NumberOfLastRow + 1, 1);
CellForNewData.InsertData(your_data);
You are explicitly storing the values in row 1 of the spreadsheet. If you want to append the values, you'll have to increment the row number and store the values in the appropriate cells.
I've encountered a problem. I'm trying to read data from xlsx document using LinqToExcel. The data is retrieved but the document has cells which are interpreted as formulas with text like "=- Something". Is it possible to get those cells text and not the counted value of the formula?
var book = new LinqToExcel.ExcelQueryFactory(path);
var worksheetNames = book.GetWorksheetNames();
var query =
from row in book.WorksheetNoHeader()
where row[0] != ""
select row;
With LinqToExcel you can't receive formula, because linqtoExcel uses OleDB to access sheet. OleDB doesn't allow to access formulas. Instead linqtoExcel you can use Worksheet.Range Property
Example:
Range range = (Range)sheet.Cells[i, j];
return range.Formula;
Please help me to fetch or to read specific cell data of .xls spreed sheet using GemBox in c#.
I am able to write but fails to read the specific cell data.
I don't want to read all data at once.
var dataSet = new DataSet();
SpreadsheetInfo.SetLicense("FREE-LIMITED-KEY");
GemBox.Spreadsheet.ExcelFile ef = new GemBox.Spreadsheet.ExcelFile();
// ExcelFile ef = ExcelFile.Load(#"C:\Users\LENOVO\Documents\100sitesSpreedSheet.xls");
ef = GemBox.Spreadsheet.ExcelFile.Load(#"C:\Users\LENOVO\Documents\100sitesSpreedSheet.xls");
ExcelWorksheet ws = ef.Worksheets["100sitesSpreadSheet"];
ws.Cells[6, 0].Value = "abcd";
ef.Save(#"C:\Users\LENOVO\Documents\100sitesSpreedSheet.xls");
to read the specific cell's value you can just use the Value property, like the following:
Console.WriteLine(ws.Cells["A7"].Value);
This property is of an object type and can return a text or a number or a date, depending on the data it stores. Also note that GetFormattedValue method actually converts that value into a string representation by using a number format which is applied to that cell.
