I am trying to retrieve the data from Excel Sheet on Sharepoint by C# Code.
I can get the value for 1 cell in the excel. But I want the range of values(the whole column). How can i get that ?
Suppose on browser, I type :
http://test.net/excel/_vti_bin/ExcelRest.aspx/docs/MyExcelFile.xlsm/Model/Ranges('Sheet2!D4')?$format=HTML
I get the cell value. But Now I want to get the every value for Column D, how can I get it ?

I'm generating excel report in c# in excel.binding data to excel through datatable.
There is one column which will consist of 16 digit number for eg.,1317722825000285 but in excel it is coming as 1317722825000280 last digit is getting replaced by 0.
So how to can I format this column value as excel Text ?
There's a great post here that may answer your question: Format an Excel column (or cell) as Text in C#?
Try formatting the cell as text and making your variable a string in C# before inserting.
Hope this helps.
I'm creating a workbook in Excel using Open XML, which works fine - except dates. Working in Excel you can change a cell's datatype like this:
Right click the cell, format cell, in the number tab choose "date" (from the category section). I'd like to accomplish the same thing using C# and Open XML to create the workbook, however my date cells are shown as "general" (text) in Excel.
The date format is OK, it's presented like this: 01.01.2015. What I need is the cell type to be set to Date, so that I can filter by "January", not the string "01.01.2015".
When saving my Excel sheet as an .xml, I find that the cell is stored like this:
<Cell><Data ss:Type="String">04.09.2015 22:00:41</Data></Cell>
What I need is this:
<Cell ss:StyleID="s62"><Data ss:Type="String">04.09.2015 22:00:41</Data></Cell>
The bottom row is from a cell where I manually manipulated the data type to a Date.
I've used the examples where you create your own styles, the cell type is still a string when opened in Excel.
Im trying to build a addin that can take some a selection of cells from a excel sheet and then put them together in the first cell i have celected. Between the cells there will be a user selected seperator.
example:
I select the 3 cells A1-A3 with the values A B and C
I then bring up my addin and chose the seperator to be ", ".
The addin should then place a the String "A, B, C" in the cell A1.
But I cant figure out how to access the data I have selected in the excel sheet.
var range = (Range)Globals.ThisAddIn.Application.ActiveWindow.Selection;

Excel convert my string values to numeric when after export. But i must see "01". How can i change excel cell type or cell value in code when before save file.?
From Excel, highlight the column or the cell, right click and select "Format Cells", under the "Number" tab, click "Custom" under the Category:. In the Type: textbox, key in "00".
You can export text with a apostrophe suffix. for e.g. to display 01 instead of 1, you need to set cell's value as '01 and not just 01
Excel will take this value as text instead of number. But in this case you will see a Error SamrtTag in Excel saying "Number stored as Text" which can be turned off from preferences.
When you read or write a cell there are two values you can look at. The first one is value (e.g. cell.Value) which is the one you are probably setting. The second is NumberFormat (e.g. cell.NumberFormat). This is a string a will represent the format of the value when displayed in Excel, set this to an appropriate value (use the string representations in Excel if you're not sure which one you want).
