RowSlice

This tool suite enables the splitting, merging, de-duplication, and encoding correction of large CSV files directly within the web browser, addressing limitations faced by spreadsheet applications like Excel that cannot handle files exceeding 1 million rows. Its main features include dividing massive CSV datasets into manageable parts based on row count or column values, merging multiple CSV files with aligned columns, removing duplicate rows, converting file encoding formats such as to UTF-8 to prevent garbled characters, and generating realistic sample CSV data for testing purposes, making it ideal for data analysts, database administrators, and developers managing large-scale data exports or imports.

RowSlice can be found in File Conversion Tools categories.
