Large CSV & XLSX File Splitter !

Job ID: 38633805

Budget: $10 – $20 USD

I need a tool that can break down my large xlsx and csv files into smaller files. The large xlsx files can be up to 4GB to 400GB in size, and the tool should output both CSV and XLSX formats. Please note that the xlsx files have a limitation where they only display up to 1 million rows.

I want a tool where I can specify to break it down to 100k or 1million rows per file (or any amount I need). And it'll keep breaking the file up until done.

- Experience with large data file manipulation
- Knowledge of CSV and XLSX file formats
