I am losing the leading zeros when I copy values from a datatable to an Excel sheet. That's because probably Excel treats the values as a number instead of text.

C# - excel - interop - numberformat. C# / C Sharp Forums on Bytes. 424,013 Members| 1,313 Online Join Now. I use c# to start excel and to get numberformat of active cell. VBA outputs results as expected, but via c# i get result 'Standard' instead of 'General'. How do I set Excel cell format to 'Text' from VB.NET?

Below is some code to format columns A and C as text in SpreadsheetGear for .NET which has an API which is similar to Excel - except for the fact that SpreadsheetGear is frequently more strongly typed. It should not be too hard to figure out how to convert this to work with Excel / COM:

If you set the cell formatting to Text prior to adding a numeric value with a leading zero, the leading zero is retained without having to skew results by adding an apostrophe. If you try and manually add a leading zero value to a default sheet in Excel and then convert it to text, the leading zero is removed. If you convert the cell to Text first, then add your value, it is fine. Same principle applies when doing it programatically.

I've recently battled with this problem as well, and I've learned two things about the above suggestions.

Setting the numberFormatting to @ causes Excel to left-align the value, and read it as if it were text, however, it still truncates the leading zero.
Adding an apostrophe at the beginning results in Excel treating it as text and retains the zero, and then applies the default text format, solving both problems.

The misleading aspect of this is that you now have a different value in the cell. Fortuately, when you copy/paste or export to CSV, the apostrophe is not included.

Conclusion: use the apostrophe, not the numberFormatting in order to retain the leading zeros.

Solution that worked for me for Excel Interop:

This code should run before putting data to Excel. Column and row numbers are 1-based.

A bit more details. Whereas accepted response with reference for SpreadsheetGear looks almost correct, I had two concerns about it:

I am not using SpreadsheetGear. I was interested in regular Excelcommunication thru Excel interop without any 3rdparty libraries,
I was searching for the way to format column by number, not usingranges like 'A:A'.

Use your WorkSheet.Columns.NumberFormat, and set it to string '@', here is the sample:

If you want a particular column to apply the text format, for example, the first column, you can do this:

or this will apply the specified range of woorkSheet to text format:

I know this question is aged, still, I would like to contribute.

Applying Range.NumberFormat = '@' just partially solve the problem:

Yes, if you place the focus on a cell of the range, you will read text in the format menu
Yes, it align the data to the left
But if you use the type formula to check the type of the value in the cell, it will return 1 meaning number

Applying the apostroph behave better. It sets the format to text, it align data to left and if you check the format of the value in the cell using the type formula, it will return 2 meaning text
