Easy way to export multiple data.frame to multiple Excel worksheets

📝 Blog Post: Easy Way to Export Multiple data.frame to Multiple Excel Worksheets

👋 Hey there tech enthusiasts! Have you ever faced the problem of exporting multiple data.frames to multiple worksheets in Excel, but couldn't find an easy way to do it? 😫 Well, you're not alone! Many developers struggle with this issue, but fear not, because in this blog post, we'll provide you with simple solutions to overcome this challenge. 💪

🤔 Understanding the Problem

🔍 One user mentioned that they tried the "xlsx" package but realized it could only write to one sheet, overriding the old sheet. They also encountered errors while using the "WriteXLS" package. So, what's the problem here? 🤷‍♀️

📝 The Code Structure

👨‍💻 The user shared their code structure, where for each iteration, the output dataframe (tempTable) and the sheetName (sn) get updated and exported into one tab. However, the desired outcome is to have each dataframe exported to separate worksheets in the Excel file. 📊

💡 The Solution: openxlsx Package

🚀 Don't worry! We have a solution that will make your life easier. The "openxlsx" package is a powerful tool that allows you to export multiple data.frames to multiple Excel worksheets effortlessly. 😎

📥 Installing the Package

To get started, you need to install the "openxlsx" package if you haven't already. Simply run the following command in your R console:

install.packages("openxlsx")

🔨 Using the Code

Now, let's dive into the code and see how we can export multiple data.frames to multiple Excel worksheets using the "openxlsx" package!

# Load the openxlsx package
library(openxlsx)

# Create a new Excel workbook
wb <- createWorkbook()

# Iterate over each data.frame
for (i in 2:ncol(code)) {
  ...
  tempTable <- ...
  sn <- ...
  
  # Add each data.frame as a new worksheet in the workbook
  addWorksheet(wb, sheetName = sn)
  writeData(wb, sn, tempTable)
}

# Save the workbook as an Excel file
saveWorkbook(wb, "file.xlsx", overwrite = TRUE)

🎉 Explanation and Example

Let's break down the code:

1. We first load the "openxlsx" package, which provides the necessary functions for working with Excel files.

2. Next, we create a new Excel workbook using the createWorkbook() function provided by the package.

3. Then, we iterate over each data.frame in your code (notice the for loop).

4. Inside the loop, we update the tempTable and sn variables with the appropriate values.

5. To export each data.frame to a separate worksheet, we use the addWorksheet() function to add a new worksheet to the workbook, and the writeData() function to write the data.frame to the corresponding sheet.

6. Finally, we save the workbook as an Excel file using the saveWorkbook() function.

Voilà! 🎉 You have successfully exported multiple data.frames to separate worksheets in Excel!
