Convert JSON data into a structured Excel (.xlsx) or CSV file with WebToolar’s free JSON to Excel Converter. Paste your JSON, upload a JSON file, or load a sample, then convert your data into a spreadsheet that is easy to view, analyze, and share.

The tool supports JSON objects, arrays, nested objects, and common JSON structures. You can also flatten nested data, preview the converted rows, search the preview, and choose your Excel sheet and file names.

What Is a JSON to Excel Converter?

A JSON to Excel converter transforms structured JSON data into rows and columns that can be opened and managed in Microsoft Excel. JSON is commonly used by APIs, web applications, databases, and software systems, while Excel is widely used for reporting, analysis, filtering, and business workflows.

Instead of manually copying JSON values into a spreadsheet, this tool automatically extracts your records and prepares them for Excel export.

How to Convert JSON to Excel

Converting JSON to an Excel spreadsheet takes only a few steps:

1. Paste your JSON into the input editor, or choose Upload File to add a JSON or TXT file.
2. Click Prettify if you want to format and indent the JSON.
3. Enable Flatten nested objects if your JSON contains nested properties.
4. Enter a custom Sheet Name and File Name if required.
5. Click Convert & Preview to process the data.
6. Review the rows and columns in the preview.
7. Click Export .XLSX or Download Excel (.xlsx) to save your spreadsheet.

The converter also provides a CSV export option and lets you copy the converted tabular data to your clipboard.

Features of Our JSON to XLSX Converter

Paste or Upload JSON

You can paste a JSON array or object directly into the editor. Alternatively, upload a .json or compatible .txt file using the drag-and-drop uploader.

Flatten Nested JSON

Nested objects can be difficult to work with in a spreadsheet. The Flatten nested objects option converts nested properties into column-friendly keys such as:

user.address.city

This helps turn hierarchical JSON structures into a more readable table.

Preview Converted Data

Before downloading your spreadsheet, you can preview the converted data in a table. The preview displays the first 100 rows, while the tool also shows the total number of rows and columns processed.

Search Your Data

Use the quick-search field to find values within the converted preview. This can be useful when working with larger JSON datasets.

Export to XLSX or CSV

After conversion, you can export your data as an Excel XLSX file or CSV file. You can also copy the converted tabular data to your clipboard.

Customize the Spreadsheet

Choose your own Excel sheet name and output file name before exporting. The converter also automatically determines suitable column widths when creating the XLSX file.

What JSON Formats Can You Convert?

The converter can process several common JSON structures.

JSON Array of Objects

This is one of the most common formats:

[
  {
    "name": "John",
    "age": 30,
    "city": "New York"
  },
  {
    "name": "Sarah",
    "age": 28,
    "city": "London"
  }
]

The records can be converted into spreadsheet columns such as name, age, and city.

JSON Object Containing an Array

The converter can also detect an object containing an array of records, such as:

{
  "data": [
    {
      "id": 1,
      "name": "Product A"
    },
    {
      "id": 2,
      "name": "Product B"
    }
  ]
}

The tool identifies an appropriate array property and processes its records for conversion.

Nested JSON

For nested data, you can enable the flattening option. For example:

{
  "name": "John",
  "address": {
    "city": "New York",
    "country": "USA"
  }
}

Can be represented with spreadsheet-friendly fields such as:

name	address.city	address.country
John	New York	USA

The converter recursively processes nested objects and handles arrays according to their structure.

JSON Array of Arrays

The converter can also interpret an array where the first row contains column headers:

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

The first array is used as the header row and the remaining arrays become records.

JSON to Excel vs JSON to CSV

Both Excel and CSV are useful for working with structured data, but they serve slightly different purposes.

Format	Best For
XLSX	Microsoft Excel, spreadsheet analysis, formatted workbook workflows
CSV	Simple tabular data, data imports, lightweight file exchange
JSON	APIs, applications, structured data, data exchange

If you need a standard Excel workbook, choose XLSX. If you need a simple comma-separated file for importing or transferring data, choose CSV.

Common Uses for Converting JSON to Excel

A JSON to Excel converter can be useful for:

• API data analysis – Convert API responses into spreadsheet rows.
• Business reports – Turn structured JSON records into Excel reports.
• Data cleaning – View JSON data in a familiar tabular format.
• Database exports – Convert exported JSON records into spreadsheets.
• E-commerce data – Organize product, order, or customer records.
