How to Convert Excel to JSON: A Complete Guide

Our Excel to JSON converter is a powerful, real-time tool that transforms your spreadsheet data into structured JSON format. JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate.

1 Upload Your Excel File

Drag and drop your .xlsx, .xls, or .csv file into the upload area or click "Browse Files" to select a file from your computer. The tool supports files up to 10MB in size.

2 Configure Conversion Options

Customize how your data is converted:

First row as property names: Uses your first row as JSON property keys
Trim whitespace: Removes extra spaces from cell values
Sheet selection: Choose which worksheet to convert (for multi-sheet files)
Row filtering: Limit conversion to specific row ranges

3 Filter and Search Data

Use the filtering options to:

Search for specific values within your data
Exclude sensitive or unnecessary columns
Skip empty rows to clean up your output

4 Preview and Export

The real-time JSON preview updates instantly as you change options. Once satisfied:

Copy the JSON to clipboard with one click
Download as a .json file for use in applications
Validate the JSON structure to ensure it's properly formatted
