Fun Fact
Column formatting dates back to early printing presses where text had to be manually arranged into narrow columns to conserve paper and improve readability.
Historical Context
Multi-column text layouts became standard during the rise of newspapers in the 17th century. In computing, column conversion utilities evolved alongside spreadsheet software in the 1980s, enabling structured data manipulation. Modern browser-based tools now perform these operations entirely on the client side, ensuring both speed and privacy.
