Exporting data to Excel from R is a common requirement, especially when you need to share your results with users who prefer working with spreadsheets. While CSV files are widely used and supported, Excel files offer additional features such as multiple sheets, formatting, and better compatibility with business tools. You might choose to export to Excel when your audience expects .xlsx files or when you want to preserve richer data structures that CSV cannot handle.

# Install the writexl package if you have not already
install.packages("writexl")

# Load the writexl package
library(writexl)

# Assume data_excel_export is your data frame
# Export data_excel_export to an Excel file named "my_data.xlsx"
write_xlsx(data_excel_export, "my_data.xlsx")

The write_xlsx() function from the writexl package allows you to export a data frame, such as data_excel_export, directly to an Excel .xlsx file. Unlike write.csv(), which creates plain text files with comma-separated values, write_xlsx() generates a true Excel file that can include multiple sheets and is fully compatible with spreadsheet software. This makes it a better choice when you need to maintain Excel-specific formatting or when your collaborators prefer Excel over CSV files.
