📝 The EPPlus Number Format Dilemma: Solving the Mystery of E+0

So, you're using EPPlus to generate an Excel sheet, and you've run into some number formatting issues. Fear not, my tech-savvy friend! 👨‍💻 I'm here to help guide you through this challenge and point you in the right direction. Let's jump right into it!

The Problem at Hand

You want to apply number formatting to a double value in your Excel sheet, specifically formatting it in a way that presents it like this:

• 8 → 8.0

• 12 → 12.0

• 14.54 → 14.5

• 0 → 0.0

Seems like a fairly straightforward task, right? Well, let's examine the code snippet you shared to see what may be causing the unexpected results:

ws.Cells[row, col].Style.Numberformat.Format = "##0.0";

The Unexpected Output

To your surprise, the final Excel file is appending "E+0" to the end of your desired format, resulting in values that look like this instead:

• 8 → 8.0E+0

• 12 → 12.0E+0

• 14.54 → 14.5E+0

• 0 → 000.0E+0

Curious about what went wrong, you decide to investigate further by checking the format cells of the generated Excel sheet. To your dismay, you notice that the format appearing is "##0.0E+2" instead of the "##0.0" you applied. 🤔

Unveiling the Mystery

The reason behind this unexpected behavior lies in a little nuance of EPPlus when it comes to number formatting. The format "##0.0" is actually interpreted as "##0.0E+2" by EPPlus.

In other words, when you specify "##0.0" as the format, EPPlus assumes you want to display the number as a scientific notation with 2 decimal places. Hence, the "E+0" suffix appearing in your output. 🧐

The Solution

Now that you understand the root cause of the problem, let's explore how you can achieve your desired formatting with EPPlus.

Instead of using "##0.0" as the format, you can use "0.0" to get rid of the scientific notation suffix. Here's the revised code snippet:

ws.Cells[row, col].Style.Numberformat.Format = "0.0";

By making this small adjustment, you'll obtain the desired output format without the pesky "E+0" suffix. Voila! 🎉
