How It Works

  1. 1

    Paste JSON Array with Objects

    Paste your JSON array where each object represents a row with consistent properties. Works with API responses, database query results, or any structured JSON data.

  2. 2

    AI Creates Excel Headers and Cells

    The tool extracts object keys as Excel column headers, maps each property value to cells, and formats numbers, dates, and booleans as appropriate Excel data types.

  3. 3

    Download XLSX for Analysis

    Download Excel file ready for pivot tables, charts, formulas, and business reporting in Excel, Google Sheets, or LibreOffice Calc.

Code Examples

Example 1: Simple Product List

JSON Input
[
  {"Product": "Laptop", "Price": 999.99, "Stock": 50, "Available": true},
  {"Product": "Mouse", "Price": 29.99, "Stock": 200, "Available": true},
  {"Product": "Keyboard", "Price": 79.99, "Stock": 0, "Available": false}
]
Excel Output
Excel Spreadsheet:

| Product  | Price  | Stock | Available |
|----------|--------|-------|----------|
| Laptop   | 999.99 | 50    | TRUE     |
| Mouse    | 29.99  | 200   | TRUE     |
| Keyboard | 79.99  | 0     | FALSE    |

Column A: Text
Column B: Number (2 decimals)
Column C: Number (whole)
Column D: Boolean

Key Changes:

JSON object keys (Product, Price, Stock, Available) become Excel column headers in row 1. Each JSON array element becomes a row. Price values format as currency with 2 decimal places. Stock integers remain whole numbers. Boolean true/false convert to Excel TRUE/FALSE enabling use in IF() formulas. The resulting spreadsheet can be sorted, filtered, and used in charts. This format is typical for e-commerce inventory exports or sales reports.

Example 2: Employee Data with Dates

JSON Input
[
  {"ID": 101, "Name": "Alice Johnson", "Dept": "Engineering", "Hire": "2024-01-15", "Salary": 95000},
  {"ID": 102, "Name": "Bob Smith", "Dept": "Marketing", "Hire": "2023-11-20", "Salary": 75000},
  {"ID": 103, "Name": "Carol White", "Dept": "Sales", "Hire": "2024-02-01", "Salary": 85000}
]
Excel Output
Excel Spreadsheet:

| ID  | Name          | Dept        | Hire       | Salary |
|-----|---------------|-------------|------------|---------|
| 101 | Alice Johnson | Engineering | 1/15/2024  | 95000  |
| 102 | Bob Smith     | Marketing   | 11/20/2023 | 75000  |
| 103 | Carol White   | Sales       | 2/1/2024   | 85000  |

Hire column: Formatted as Date
Salary column: Formatted as Currency

Key Changes:

ISO date strings (2024-01-15) are detected and converted to Excel date format, enabling date arithmetic and sorting by hire date. Salary numbers format as currency for financial reporting. The ID column remains integer. Text fields (Name, Dept) allow filtering and pivot tables. In Excel, you can now use formulas like =SUM(E:E) to total salaries or create pivot tables grouped by department. This conversion is essential for HR reports and payroll processing from JSON database exports.

Frequently Asked Questions

How are JSON arrays converted to Excel rows?

JSON arrays convert to Excel rows where each array element becomes a row. Object properties become columns with headers. For example, [{"name": "John", "age": 30}] creates a 2-column spreadsheet with 'name' and 'age' headers. Nested objects flatten or appear as text in cells.

Can it handle large JSON datasets?

Yes. The converter processes large JSON arrays efficiently, creating Excel files with thousands of rows. Excel has a 1,048,576 row limit per sheet. For larger datasets, consider splitting JSON or using CSV format. Modern browsers handle files up to several MB client-side.

Are data types preserved in Excel?

JSON types map to Excel types: numbers become numeric cells, strings become text, booleans become TRUE/FALSE, and null becomes empty cells. Dates in ISO format (2024-01-15) are detected and formatted as Excel date cells. This enables Excel formulas like SUM() and sorting.
