How Can I Accurately Retrieve DateTime Values from Excel Spreadsheets Stored as Doubles?

Retrieve Accurate Datetime Values from Excel Spreadsheets

When working with Excel spreadsheets, it's crucial to correctly extract datetime values to preserve their accuracy. However, encountering a double value when attempting to read a datetime can be frustrating. To rectify this issue, let's delve into a solution that ensures the retrieval of precise datetime values.

The issue arises when the datetime value is stored in Excel's OLE Automation format, which is represented as a double. To convert this double value into the .net datetime format, we employ the DateTime.FromOADate method. This method enables the transformation of OLE Automation dates into their corresponding .net datetime equivalents.

By implementing the following code, you can effortlessly convert double values to accurate datetime values:

double d = double.Parse(b);
DateTime conv = DateTime.FromOADate(d);
Copy after login

In this code, d represents the double value extracted from the Excel spreadsheet, while conv stores the converted datetime value. This approach ensures the preservation of the original datetime's precision and allows for seamless further processing or display within your application.

C# vs. C  : History, Evolution, and Future Prospects C# vs. C : History, Evolution, and Future Prospects Apr 19, 2025 am 12:07 AM

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.

C# vs. C  : Learning Curves and Developer Experience C# vs. C : Learning Curves and Developer Experience Apr 18, 2025 am 12:13 AM

There are significant differences in the learning curves of C# and C and developer experience. 1) The learning curve of C# is relatively flat and is suitable for rapid development and enterprise-level applications. 2) The learning curve of C is steep and is suitable for high-performance and low-level control scenarios.

What is static analysis in C? What is static analysis in C? Apr 28, 2025 pm 09:09 PM

The application of static analysis in C mainly includes discovering memory management problems, checking code logic errors, and improving code security. 1) Static analysis can identify problems such as memory leaks, double releases, and uninitialized pointers. 2) It can detect unused variables, dead code and logical contradictions. 3) Static analysis tools such as Coverity can detect buffer overflow, integer overflow and unsafe API calls to improve code security.

C   and XML: Exploring the Relationship and Support C and XML: Exploring the Relationship and Support Apr 21, 2025 am 12:02 AM

C interacts with XML through third-party libraries (such as TinyXML, Pugixml, Xerces-C). 1) Use the library to parse XML files and convert them into C-processable data structures. 2) When generating XML, convert the C data structure to XML format. 3) In practical applications, XML is often used for configuration files and data exchange to improve development efficiency.

Beyond the Hype: Assessing the Relevance of C   Today Beyond the Hype: Assessing the Relevance of C Today Apr 14, 2025 am 12:01 AM

C still has important relevance in modern programming. 1) High performance and direct hardware operation capabilities make it the first choice in the fields of game development, embedded systems and high-performance computing. 2) Rich programming paradigms and modern features such as smart pointers and template programming enhance its flexibility and efficiency. Although the learning curve is steep, its powerful capabilities make it still important in today's programming ecosystem.

How to use the chrono library in C? How to use the chrono library in C? Apr 28, 2025 pm 10:18 PM

Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron
