Tired of copy-pasting data from dozens of spreadsheets? Excel & CSV Merger combines any number of .xlsx, .xls and .csv files into one clean file in seconds.

Columns are matched by name, not by position. Files with a different column order, extra columns or slightly different headers ("Name", "name ", "NAME") still line up perfectly. Columns missing in some files are simply left empty.

What it does:

- Merges unlimited files and rows: monthly reports, CRM exports, survey results, sales data

- Merges all sheets of each workbook, or only the first one — your choice

- Adds a "Source" column, so you always know which file every row came from

- Removes duplicate rows (optional)

- Saves as Excel (.xlsx) or CSV (comma or semicolon separated)

- Keeps dates as real Excel dates and preserves leading zeros in ZIP codes and IDs

- Auto-detects CSV encodings: UTF-8, UTF-16, Windows-1251, Windows-1252

Works 100% offline — your files never leave your computer. Safe for sensitive business data.

What you get:

- Windows installer (Windows 10/11, 64-bit)

- Personal license key, delivered instantly with your purchase

- Free updates — the app tells you when a new version is available
