During exporting excel from gridview the data of a column known as Account Number prefixes 0 are removed. Please guide me for the same
You need to get Account number into a string variable so as to protect leading zero, then while exporting to excel, you need to set cell type to string before you set the value to cell.

I am trying to create .csv out of Excel which would have columns A - H filled with some data I want to read but data is optional. So some times the first column A can be empty. Now, when I save the .csv, unless I entered one space in the A column, Excel automatically trims A column, and the result is 7 cells to read A - G instead 8 cells A - H (with A column) being "empty". I would like to save client the trouble of needing to enter one space or -> ="" in the Excel formula to make first or last column "empty" but not trimmed in the resulting .csv.
Thank you!
There is no option in Excel to preserve empty columns, when exporting to .csv. But you could introduce a header text in the first row, so you will always have the columns filled atleast with the header text.
Plus it would make your data probably more readable, depending on what data this is.
Another possibility would be to implement a makro and embedd a button in your excel file:

I have an excel file with a column of names and a column of numbers.
I had imported the excel into the Datagrid and manage to find the maximum number among from the column.
For example, the cell which is the maximum is at (x,y).
How do I get the program to know the cell and display the name in the same row?
I want to convert the data of Excel file in the DataTable for edit. But cells with formulas should not be editable. How do I find that the cell contains a formula, if I get the calculated value in it? Thanks.
Try the .HasFormula property of Range

Range.SpecialCellsmethod enables to get cells with constant values or formulas.
I am using linqtoexcel for reading from a excel sheet. the problem i face is that i can't read the formula calculated value from a cell, instead i get the actual value of the cell. Is there any way to read the end value of the cell from the excel sheet using linqtoexcel or by some other means.
linqtoexcel uses OleDB to access the sheet's data, and since OleDB does not allow the formulas to be accessed, you can't read the formula from the excel cell. You can only view the value for the cell.
I have .xlsx document in which I need to import some values to cells with defined names. Few of those cells are formatted as currency and values that I am importing in those cells are of decimal type which I import in this manner:
cell.CellValue = new CellValue(value.ToString().Replace(",", "."));
In the same spreadsheet there are a few cells that have a formula in which currency cells I imported are used (eg., I am importing value in cell H27 with defined name Total, and in the field I27 there is a formula =Total*0.23).
After import is complete, values are successfully imported (and correctly formatted as currency), but formula cells are not correctly calculated until I either click on formula check marks for each formula cell or I change the currency value (in this case, all formulas containing this cell are refreshed).
What do I have to do for cells with formulas to automatically calculate values after import is completed?
I've figured it out. The cells with formula have <CellFormula> fields inside of them. Those fields have bool attribute CalculateCell which, if set to true, tells Excel to calculate the formula after opening the file. Since I don't know up front which formula cells are affected by the cells, I manage all of them like this:
foreach (var cell in sheetData.Descendants<CellFormula>())
cell.CalculateCell = true;
