Can I choose how nested JSON is laid out in the Excel file?

Yes. Use the Output layout option to control how nested JSON becomes rows and columns: Table (default) - one column per field, one row per record; best for flat or lightly nested JSON. Key / Value - two columns (the field path and its value), one row per value; handy for deeply nested or irregular JSON. One row per element - every value on its own row with its full path; useful for flattening or auditing. Nested levels - the path is split across columns (level 1, level 2, and so on) followed by the value; good for pivot-style analysis. One row per record - keeps each record on a single row and spreads repeating nested lists into indexed columns (for example line_items/0/amount, line_items/1/amount); best when every object should stay one row even with nested arrays.

Can I convert a large JSON file to Excel?

Yes. Our Free JSON to Excel Online Converter handles large JSON files that browser-only tools cannot - the conversion runs on our servers, not in your browser's memory, so big API exports and data dumps convert without crashing or hitting a small upload cap. Note that the Excel XLSX format itself holds up to 1,048,576 rows per sheet; if your data exceeds that, convert to CSV instead, which has no row limit.

Do I need to install any software to convert JSON to Excel?

No. The JSON to Excel Converter runs online in your web browser - there is nothing to download or install, and it works on Windows, macOS, Linux and Chromebook. Upload your JSON file, run the conversion and download the Excel spreadsheet in .xlsx or .xls format. Your files are encrypted in transit and deleted automatically after conversion.

Convert Large or Nested JSON to Excel - Nothing to Install

Many online JSON tools run entirely in your browser, which is fine for a small snippet but falls over on real-world data. Our converter processes your file on the server, so it handles large JSON exports and deeply nested structures that browser-only tools cannot.

Large files: Convert big API responses, database exports, and data dumps without hitting a small upload cap or running out of browser memory.
Nested JSON, your way: The Output layout option lets you decide exactly how nested objects and arrays become rows and columns - keep every record on one row, spread repeating lists into indexed columns, or flatten it fully.
No software to install: Everything runs in your browser on Windows, macOS, Linux, or Chromebook - no downloads, no admin rights, no setup.
Private by design: Files are encrypted in transit, source files are deleted right after conversion, and results are removed automatically within 24 hours.

The XLSX format itself holds up to 1,048,576 rows per sheet. If your dataset is larger, convert to CSV instead, which has no row limit.

Why Should You Transform JSON to Excel?

It is difficult to read and comprehend JSON even though it is a text format. Our service can assist in this case by converting JSON into Excel table. As a result, it becomes easy to read, understand and do required data manipulations like filtering and applying formulas.

JSON File Format

JavaScript Object Notation is the full meaning of JSON. This is a text document that can be created in any text editor. It is a popular text-based technique for presenting structured data in JavaScript object syntax.

JSON Format Description

This format contains different types of data: objects, arrays, and attributes.

The Attribute is a key-value, where the key is the name of the attribute. Attributes can only be used inside objects.

For example:

json

{
  "type": "book"
}

The Object is a data structure with a set of attributes on the same level.

For example:

json

{
  "type": "book",
  "name": "Book of success",
  "price": "24.99"
}

And Array is a set of objects.

For example:

json

[
  {
    "type": "book",
    "quantity": 5
  },
  {
    "type": "magazine",
    "quantity": 12
  }
]

Where is the JSON Format Applicable?

It is a commonly used format for internet services, APIs, websites. The JavaScript Object Notation file can be used to store and configure data. It can as well be used for data interchange between different applications.

JSON is one of the most popular formats used on the Internet - for data interchange between websites or internet services or APIs.

Format Resources

JSON.org - Official JSON specification
RFC 8259 - The JSON Data Interchange Format (IETF)

How Exactly Does the Converter Work?

We transform objects in JSON into a flat table layout in accordance to specified rules, with arrays acting as a collection of rows in the table.

Nested JSON rarely maps cleanly onto a single flat table. The Output layout option lets you choose exactly how nested fields become rows and columns in the Excel. Pick the shape that matches how you will use the data:

Tabletable

One column per field, one row per record. The default, and the best fit for flat or lightly nested JSON.

Input (JSON)

json

{
  "order": {
    "id": "1001",
    "status": "paid",
    "item": { "sku": "A1", "qty": "2" }
  }
}

Output (Excel)

order	id	status	item	sku	qty
	1001	paid		A1	2

Key / Valuekey_value

Two columns, the field path and its value, with one row per value. Ideal for deeply nested or irregular JSON where a fixed set of columns does not fit.

Input (JSON)

json

{
  "order": {
    "id": "1001",
    "status": "paid",
    "item": { "sku": "A1", "qty": "2" }
  }
}

Output (Excel)

key	value
order/id	1001
order/status	paid
order/item/sku	A1
order/item/qty	2

One row per elementelement_rows

Every value on its own row alongside its full path. Useful for flattening or auditing all values in one long list.

Input (JSON)

json

{
  "order": {
    "id": "1001",
    "status": "paid",
    "item": { "sku": "A1", "qty": "2" }
  }
}

Output (Excel)

path	text
order/id	1001
order/status	paid
order/item/sku	A1
order/item/qty	2
order/item
order

Nested levelspath_levels

The path is split across columns (level 1, level 2, and so on) followed by the value. Good for pivot-style analysis by depth.

Input (JSON)

json

{
  "order": {
    "id": "1001",
    "status": "paid",
    "item": { "sku": "A1", "qty": "2" }
  }
}

Output (Excel)

level_1	level_2	level_3	value
order	id		1001
order	status		paid
order	item	sku	A1
order	item	qty	2
order	item
order

One row per recordNewtranspose

Keeps each record on a single row and spreads repeating nested lists into indexed columns (for example line_items/0/amount, line_items/1/amount). The best fit when every record must stay one row even with nested arrays.

Input (JSON)

json

{
  "order": [
    { "id": "1001", "item": [ { "sku": "A1" }, { "sku": "B7" } ] },
    { "id": "1002", "item": [ { "sku": "C3" } ] }
  ]
}

Output (Excel)

order	id	item/0	item/0/sku	item/1	item/1/sku
	1001		A1		B7
	1002		C3
