asp.net – How do I prevent data from displaying in scientific format?

Posted by: admin May 14, 2020 Leave a comment


I have this sql server query that I am running in my .net app.

(CONVERT(VARCHAR(8), EventDate, 112)+ substring(RequestedBy,1,1)+right( '0000000' + convert( varchar( 7 ), ContactID ), 7 )) as Contacts

It produces the following results in the following format:


This is the result and format that we want.

Problem is when we click on export icon to export these results to excel, the first one changes to the scientific format like 2.01E+08.

Any date that has e in the middle such as 20120731*e*0000001 turns into scientific data.

The rest is just fine.

Any ideas how to fix this?

I want to apologize in advance if I stick the wrong tag in the Tags section since I am not sure where the fix could come from.

How to&Answers:

When you open the exported data file directly with Excel, all formats are set as General. In General format, Excel applies formatting to what it recognizes as numbers and dates. So, to be clear, the issue is not with your export, but rather with how Excel is reading your data by default. Try the following to get around this issue.

Export to CSV. Then, rather than opening the CSV in Excel, use Excel’s ‘Get External Data From Text‘ tool to import the data into an empty workbook. Here you can specify to treat this field as TEXT rather than as GENERAL.

Note that once Excel applies number (or date) format to a cell, the data in the cell has been changed. No application of a new format will bring back your desired data. For this reason you must specify the format before Excel opens the file.


The formatting is happening when Excel opens your exported file. Simply change the column to have “formatted text” of string so that it displays as the original format.
