Convert Excel to JSON quickly and easily with WebToolar’s free online Excel to JSON Converter. Upload your Excel spreadsheet and transform rows and columns into structured JSON data that you can use in APIs, applications, databases, scripts, and development projects.

Whether you are working with an XLSX or XLS spreadsheet, converting Excel data to JSON saves you from manually restructuring rows and columns into JSON objects.

What Is an Excel to JSON Converter?

An Excel to JSON converter transforms spreadsheet data from Microsoft Excel into JSON (JavaScript Object Notation), a lightweight and widely used format for storing and exchanging structured data.

For example, an Excel spreadsheet like:

Name	Age	City
John	30	New York
Sarah	28	London

can be converted into JSON:

[
  {
    "Name": "John",
    "Age": 30,
    "City": "New York"
  },
  {
    "Name": "Sarah",
    "Age": 28,
    "City": "London"
  }
]

Each spreadsheet row becomes a JSON object, while the column headers are used as JSON property names.

How to Convert Excel to JSON

Using the Excel to JSON converter is simple:

1. Upload your Excel file to the converter.
2. Select the appropriate worksheet if the tool provides multiple-sheet support.
3. Review the spreadsheet data.
4. Start the conversion.
5. Preview the generated JSON.
6. Copy or download the JSON output.

You do not need to manually write JSON syntax or convert each Excel row individually.

Convert XLSX to JSON Online

XLSX to JSON conversion is useful when spreadsheet data needs to be transferred into a web application, API, database, or programming environment.

Excel is convenient for people to organize and analyze data, while JSON is commonly used by software applications to exchange structured information. Converting between the two formats makes it easier to move data from spreadsheet-based workflows into technical systems.

Common XLSX to JSON Use Cases

• Convert Excel records for an API
• Import spreadsheet data into a web application
• Prepare Excel data for JavaScript applications
• Convert product catalogs into JSON
• Transform customer or employee records
• Convert inventory spreadsheets into structured data
• Prepare spreadsheet data for databases
• Create JSON test data from Excel
• Convert reports into machine-readable data

Excel to JSON for Developers

JSON is frequently used in modern web development because it represents structured data using objects, arrays, keys, and values.

For example, an Excel sheet containing product information can become:

[
  {
    "id": 101,
    "product": "Laptop",
    "price": 75000,
    "stock": 25
  },
  {
    "id": 102,
    "product": "Keyboard",
    "price": 2500,
    "stock": 80
  }
]

This structure can then be used in JavaScript, REST APIs, web applications, backend systems, and other software workflows.

Why Convert Excel to JSON?

Easy Data Exchange

JSON is widely supported by programming languages, APIs, databases, and web applications. Converting Excel data into JSON makes spreadsheet information easier for software systems to consume.

Save Time

Manually converting hundreds or thousands of spreadsheet rows into JSON is slow and error-prone. An automated converter can transform the data much faster.

Useful for APIs

If you have data stored in Excel but need to work with an API or web application, converting the spreadsheet to JSON provides a structured format suitable for many API workflows.

Preserve Spreadsheet Structure

Column headers can be used as JSON keys, while each row can become an individual JSON object. This creates a straightforward mapping between spreadsheet and JSON data.

Excel to JSON Example

Suppose your Excel file contains:

ID	Name	Email	Status
1	Amit	[email protected]	Active
2	Priya	[email protected]	Active
3	Rahul	[email protected]	Inactive

The resulting JSON can look like:

[
  {
    "ID": 1,
    "Name": "Amit",
    "Email": "[email protected]",
    "Status": "Active"
  },
  {
    "ID": 2,
    "Name": "Priya",
    "Email": "[email protected]",
    "Status": "Active"
  },
  {
    "ID": 3,
    "Name": "Rahul",
    "Email": "[email protected]",
    "Status": "Inactive"
  }
]

This format is easier to use in applications and automated data-processing workflows.

XLS vs XLSX to JSON

Excel files commonly use the .xls and .xlsx extensions.

• XLS – The older Microsoft Excel workbook format.
• XLSX – The newer XML-based Excel workbook format.

If your converter supports both formats, you can convert either type of spreadsheet into JSON without manually recreating the data.

Excel to JSON vs CSV to JSON

Excel and CSV files both store tabular information, but they are not identical.

Format	Common Use
Excel (XLS/XLSX)	Spreadsheets, reports, formulas, business data
CSV	Simple tabular data exchange
JSON	APIs, applications, structured data

If your data is already stored in an Excel workbook, an Excel to JSON converter can help transform it directly into JSON without first converting the workbook to CSV.

Who Can Use an Excel to JSON Converter?

An online Excel to JSON converter can be useful for:

• Developers working with APIs and application data
• Data analysts transforming spreadsheet datasets
• Web developers preparing data for websites
• Businesses converting operational spreadsheets
• Students working with structured datasets
• Researchers transforming tabular data
• E-commerce users converting product or inventory data
• Database administrators preparing spreadsheet records for import

FAQs: Excel to JSON

How do I convert Excel to JSON?

Upload your Excel spreadsheet to an Excel to JSON converter, process the spreadsheet, and export or copy the resulting JSON data.
