# Memory Usage Metrics in Excel (XlsIO) Library

This section reports the peak memory usage (RAM) observed when handling text, date and time, number, boolean, and formula data types during Create & Save and Load & Read operations.

## Test Environment

* **OS:** Windows 11
* **Processor:** AMD Ryzen 5 7520U with Radeon Graphics (2.80 GHz)
* **Installed RAM:** 16 GB (15.3 GB usable)
* **System type:** 64-bit OS, x64 processor

## Create and Save

The table below shows the peak memory usage (RAM) while creating and saving an Excel document containing 100,000 rows and 50 columns for different data types.
