How Each Tool Handles 10 Million Rows: Pandas vs Spreadsheet vs DataOlllo

The Row Limit Problem

Excel caps at 1,048,576 rows. Google Sheets caps at 10 million cells. Most cloud analytics tools impose upload limits.

How Each Tool Handles 10 Million Rows

Most data tools are designed for small datasets. When you work with files containing millions of rows, standard tools hit their limits.

Pandas

Python pandas loads the entire file into memory. For 10 million rows, this can exhaust your RAM and cause freezes.

Traditional Spreadsheets

Excel caps at 1,048,576 rows. Google Sheets caps at 10 million cells.

DataOlllo

DataOlllo uses a memory-mapped file architecture that reads only the rows and columns you actually request directly from disk.
