Excel to R DataFrame Converter

About the Excel to R DataFrame Converter

This free Excel to R DataFrame converter turns any Excel spreadsheet into clean, reusable R code. Upload your Excel file and instantly generate a data.frame() definition you can paste into R, RStudio, or your analysis scripts.

Key Features & Benefits

• Direct Excel to R code: Automatically builds a df <- data.frame(...) statement with one vector per column.
• Header-aware conversion: Use the first row as column names or auto-generate variable names when your sheet has no header.
• Valid R identifiers: Cleans column names to valid R variable names (replaces spaces and special characters).
• Ready-to-run output: Copy the generated R DataFrame definition and run it immediately in your R environment.
• Download & reuse: Save the generated R script as a .R file for version control and sharing.
• Fully browser-based: No registration, no installation, and no server-side processing.

How to Convert Excel to an R DataFrame

1. Upload your Excel file: Click the upload area or drag and drop an .xlsx or .xls worksheet.
2. Select header behavior: If your first row contains column names (e.g., customer_id, age, country), leave First row is header checked.
3. Review the generated R code: The tool builds a data.frame with one c(...) vector per column, using your Excel values.
4. Copy or download: Copy the code into R/RStudio or download it as an output.R script.
5. Run your analysis: Source the script or paste it into your R console to create the DataFrame and start analyzing.

Example: Excel to R DataFrame Code

Suppose your Excel sheet has columns:

• id
• name
• score

The generated R DataFrame might look like:

df <- data.frame(
  id = c("1", "2", "3"),
  name = c("Alice", "Bob", "Charlie"),
  score = c("85", "92", "78")
)

You can then convert columns to numeric types with as.numeric() or factors with factor() inside R, depending on your analysis.

When to Use the Excel to R DataFrame Tool

• Data science onboarding: Bring business Excel sheets into R quickly without manually typing vectors.
• Reproducible research: Replace manual copy-paste workflows with a scripted, reproducible R DataFrame definition.
• Teaching & tutorials: Share small, self-contained DataFrames as code in blog posts, courses, or documentation.
• Unit tests & mocks: Generate small R DataFrames from Excel to use as test fixtures in your R packages.
