Converting CSV to XLSX in Lightning Web Components while preserving data types requires complex parsing and type detection logic because CSV format inherently loses data type information.
Here’s how to bypass CSV conversion entirely and export Salesforce data with native data type preservation.
Export Salesforce data directly to Excel with preserved formatting using Coefficient
Coefficient provides a superior solution by bypassing CSV entirely. Instead of CSV-to-XLSX conversion, Coefficient directly exports Salesforce data with native data type preservation, eliminating the technical complexity of CSV parsing and type inference while ensuring complete data integrity.
How to make it work
Step 1. Install Coefficient and connect to Salesforce.
Add the Coefficient Excel add-in and authenticate with your Salesforce org. This creates a direct connection that maintains field metadata and data types.
Step 2. Choose your data source.
Select from any Salesforce object, report, or create a custom query. Coefficient automatically handles data type detection based on Salesforce field metadata rather than guessing from CSV content.
Step 3. Configure your export settings.
Apply any needed filters using the visual filter builder. You can filter by multiple criteria with AND/OR logic without writing custom code.
Step 4. Export with automatic data type preservation.
Run the export and Coefficient automatically preserves leading zeros for text fields, maintains proper date formatting, preserves number field precision, formats picklist values correctly, and handles boolean fields appropriately.
Eliminate CSV conversion complexity
This eliminates the need for CSV parsing, type inference logic, and manual XLSX cell formatting while ensuring 100% data integrity from Salesforce to Excel. Try Coefficient to streamline your data export process.
