unable to get original cell value from a "number stored as text"

[Guest]

I am running against a little issue. I have an excel spreadsheet, that I need to be able to read in C#. No problem there. The issue is that the system creating the spreadsheet uses a particular trick to format a number, so that the leading "0" is intact and displays. For example, the system writes a '02.7 so that excel displays 02.7.

When I travers the Range and read the value of the cell in c# or even the VBA Macro editor built into Excel, I get the numerical 02.7. I do not get the text (with leading apostrophe) '02.7. I need the full text. Does anyone know how excel stores the original data in the cell and how to get it back. I noticed that there is a little green triangle in the top, left corner of the cell. This has an error called "Number Stored as Text" I have tried looking at the range's error object with no luck.

Here is how I am getting the value in c
Excel.Range rngCurrent =
exlRange.get_Range("B3", System.Reflection.Missing.Value);

rngCurrent.Value2.ToString()

Thanks!!

Can you infer the apostrophe if the first character is"0". Perhaps using
the IsNumeric function to make sure it's not alphanumeric?

Unfortunately we can not loop through each cell, as these worksheets are very large. We are sucking out the data in bulk. Calliing a function each time would be very time consuming. When looping through each cell in a worksheet, extraction of the data takes over 2-3 minutes on a very fast box.
