Convert your Excel files to JSON format using our free online tool. Transform complex workbooks into structured, developer-friendly JSON data while maintaining data integrity. No Signup Required.
Excel (XLSX) files are based on the Office Open XML format, which is a zipped, XML-based file format developed by Microsoft.
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.
While Excel files can store complex calculations, charts, and styling, JSON files provide structured data that's ideal for web applications, APIs, and data integration.
Converting from Excel to JSON creates a programming-friendly version of your data that can be easily imported into web applications, databases, and other software systems.
JSON has become the standard data format for most modern web APIs and applications, making it invaluable for developers working with data from various sources.
Converting Excel to JSON involves extracting tabular data from Excel's complex structure and transforming it into a hierarchical JSON structure.
Excel conversion tools use libraries like pandas, openpyxl, or xlrd to read Excel's binary format and extract cell values from worksheets.
During conversion, formulas are calculated to their final values, and column headers typically become JSON property names.
Advanced converters can handle multiple worksheets by creating nested JSON objects or arrays with appropriate identifiers for each sheet.
Unlike CSV which stores everything as text, JSON maintains data types such as numbers, booleans, nulls, arrays, and nested objects, making it more suitable for complex data structures.
An online Excel to JSON converter allows you to quickly transform Excel workbooks into JSON format without installing specialized software. It's convenient for creating structured data that can be easily consumed by web applications and APIs from any device with a browser.
Our converter maintains data integrity during conversion. While Excel-specific formatting and formulas won't be carried over, all your tabular data will be accurately represented in the resulting JSON file with proper data types preserved where possible.
Conversion time depends on the file size and complexity. Most Excel to JSON conversions complete within seconds, even for larger files with many rows and columns.
