What is CSV Merger?
A CSV merger is an online tool that combines multiple CSV files either vertically (appending rows) or horizontally (adding columns). Whether you're a data analyst consolidating reports, a developer combining data sources, or a business user aggregating spreadsheets, our merger unifies CSV files into a single dataset.
This tool supports vertical merging (combining rows from multiple CSVs with the same columns) and horizontal merging (adding columns from multiple CSVs side-by-side). Handle multiple data sources efficiently by merging them into one comprehensive CSV file.
