Wide to Long Format Converter

Overview

Transform data from wide to long format (also known as “tidy data”) with interactive column selection. Long format is essential for many statistical analyses and visualization libraries like ggplot2, dplyr, and tidyr. Choose which columns to keep as identifiers and which to pivot, customize variable and value column names, then export your transformed data.
