Splitting .csv files that exceed Excel's row limit

Best tool for the job I've found: Open Source CSV File Splitter (OSV)

Very quick and easy to use. Specify lines per chunk file and you're good to go.

Keep in mind many office suites (OpenOffice/LibreOffice) have row limits around 65k (pre 3.3.3: limit is 65,536 rows | 3.3.3 and later: 1,048,576 rows)

In Excel 2010, the maximum worksheet size is 1,048,576 rows.
