Reading Datetime value From Excel sheet

📝 The Ultimate Guide to Reading DateTime Values from an Excel Sheet 🗓️

Are you facing difficulties while trying to read DateTime values from an Excel sheet? Don't worry, you're not alone! Many developers encounter similar issues when dealing with Excel data.

🔍 The Problem: The problem in this case is that when reading a DateTime value from an Excel sheet, it is being returned as a double value instead of the expected DateTime format. Additionally, when converting this double value to a Timespan, the resulting DateTime is incorrect, displaying a different value.

🚀 The Solution: To obtain the exact same DateTime value as displayed in the Excel sheet, follow these steps:

1️⃣ Step 1: Retrieving the Double Value Instead of directly converting the cell value to a double, retrieve it as a generic object using the .Value2 property. This approach ensures that the value is not automatically converted to a specific data type.

2️⃣ Step 2: Converting the Double to a DateTime To convert the double value to a DateTime, use the AddDays() method on a new DateTime object set to January 1, 1900. Add the double value as the number of days since January 1, 1900:

double doubleValue = (double)(range.Cells[rCnt, cCnt] as Excel.Range).Value2;
DateTime dateTimeValue = new DateTime(1900, 1, 1).AddDays(doubleValue);

3️⃣ Step 3: Formatting the DateTime If you require a specific DateTime format, you can use the .ToString() method to format the DateTime value accordingly:

string formattedDateTime = dateTimeValue.ToString("yyyy-MM-dd hh:mm:ss.fff");

🔀 Example: Let's say we have a cell in Excel containing the value "2007-02-19 14:11:45.730". After applying the solution, the resulting formattedDateTime would be equal to "2007-02-19 14:11:45.730".
