How to Convert Excel to JSON: A Developer's Guide

For developers, table data is often needed as JSON: APIs, config files, and in-app data flows expect JSON. Converting Excel to JSON bridges that gap.

Quick answer

Convert your Excel file with the Excel to JSON converter; each row becomes an object and column headers become keys.

Tips for clean JSON

• Keep column headers simple and consistent (they become keys).
• Check number and date formats.
• Decide whether empty cells should be null or empty strings.

When JSON, when CSV?

Use JSON for APIs and nested data; CSV is better for simple imports.

Frequently asked questions

Do multi-sheet workbooks work?

Converting per sheet gives the cleanest result.
