Introduction
In NetSuite, saving files directly from a Client Script (CS) is not possible because the N/file module is only available on the server side. To work around this limitation, you can send file data from the browser to a Suitelet, which then saves the file to the File Cabinet using server-side APIs.
This article demonstrates how to implement this pattern, including example code, best practices, and a brief introduction to JavaScript file objects used in the browser.
