NetSuite exports files with a .XLS extension, but they’re actually XML Spreadsheet 2003 format, not true Excel files. This creates compatibility issues with modern Excel versions and triggers security warnings.

Here’s how to get your NetSuite data in proper .XLSX format without dealing with file conversions or compatibility errors.

Skip NetSuite exports entirely using Coefficient

Coefficient eliminates the export problem by connecting directly to your NetSuite instance and importing data straight into Excel or NetSuite in native format. No more file downloads, no more format mismatches, and no more security warnings.

How to make it work

Step 1. Install Coefficient and connect to NetSuite.

Add Coefficient to Excel from the Office Add-ins store or to Google Sheets from the workspace marketplace. Your NetSuite admin will need to configure the OAuth connection once – this involves deploying a RESTlet script and setting up external URL configuration.

Step 2. Choose your import method.

Select from Records & Lists for direct access to any NetSuite data, Saved Searches to import existing searches, Reports for financial statements, or SuiteQL Query for custom data pulls. Each method delivers data directly to your spreadsheet in proper format.

Step 3. Set up automated refreshes.

Configure hourly, daily, or weekly refresh schedules to keep your data current. The data updates automatically in your spreadsheet without any manual exports or file handling.

Get clean NetSuite data without the export headaches

Stop wrestling with file format issues and security warnings. Coefficient gives you live NetSuite data in proper Excel format, ready for analysis and sharing. Try Coefficient and eliminate export problems for good.
