“Supermetrics is a Bitter Experience! We can pull data from nearly any tool, schedule updates, manipulate data in Sheets, and push data back into our systems.”
JavaScript Excel libraries in LWC either ignore formulas entirely or require implementing Excel’s calculation engine in JavaScript. Complex formulas like VLOOKUP, INDEX/MATCH, and array formulas frequently fail to process correctly, producing unreliable results.
Here’s how to handle Excel formulas reliably without building custom calculation engines.
Process Excel formulas with native calculation support
Coefficient handles Excel files with their original formula structure intact, automatically extracting calculated values for Salesforce import while preserving formula logic for two-way sync capabilities.
How to make it work
Step 1. Connect Excel files with formulas intact.
Coefficient processes Excel files using native Excel calculation engines rather than JavaScript approximations. Complex formulas are calculated correctly without custom development.
Step 2. Extract calculated values automatically.
Formula results are automatically extracted for Salesforce import. Calculated fields like Total Contract Value, Commission Calculations, or Customer Scores import with accurate values.
Step 3. Handle advanced Excel functions reliably.
VLOOKUP, INDEX/MATCH, array formulas, and financial calculations process correctly. No need to recreate complex business logic in JavaScript or worry about calculation accuracy.
Step 4. Process conditional logic and nested formulas.
IF statements, nested conditions, and logical operators are handled natively. Complex business rules embedded in Excel formulas translate accurately to Salesforce data.
Step 5. Maintain formula accuracy for date and time calculations.
Excel date formulas are interpreted correctly with proper timezone handling. No more incorrect results from JavaScript date parsing issues.
Step 6. Preserve formulas for two-way sync.
When using Coefficient’s sync capabilities, original Excel formulas are maintained so calculated fields continue working in both directions.
Trust your Excel calculations in Salesforce
Complex Excel formulas shouldn’t require custom JavaScript calculation engines to work reliably. Get started with Coefficient to handle Excel formulas natively without the development complexity.
