What is Csv Split?
↑File splitting divides a single file into multiple separate files based on your specifications. You can split by page ranges, by specific page numbers, into equal parts, or by file size. This is essential for extracting specific sections from large documents, creating separate handouts from a comprehensive document, or meeting file size requirements for uploads and emails.
Whether you're a student, professional, or small business owner, this tool is designed to handle your data processing needs efficiently and securely. No technical expertise required — just upload and go.

💡 Tips & Best Practices
- Double-check page numbers before splitting to ensure you extract the right content
- For recurring splits with the same structure, note down the page ranges for future use
- Name split files descriptively (e.g., 'Chapter-1.pdf' instead of 'split-001.pdf')
- Preview each split section to verify completeness before sharing
- Consider using bookmarks in the original file to identify natural split points
