JSON
JavaScript Object Notation. A lightweight, text-based format for structured data. Uses nested objects and arrays of key–value pairs. The de-facto standard for APIs, config files, and database exports.
JSON to Excel Converter
A browser-based JSON to Excel converter — real .xlsx, no upload, no signup, instant download.
Formats involved
Excel
Microsoft Excel Worksheet (XLS/XLSX). A spreadsheet format that stores data in cells organized by rows and columns. Supports formulas, formatting, and multiple sheets.
What Is JSON to Excel Conversion?
JSON to Excel conversion turns nested, hierarchical JSON data into the rows and columns of a spreadsheet. Each object becomes a row, each field becomes a column, and nested structures are flattened so the result opens directly in Microsoft Excel, Google Sheets, or any spreadsheet app as a clean .xlsx file.
Why Convert JSON to Excel?
Six reasons teams turn JSON into spreadsheets
Share Data Easily
Not everyone reads JSON. A spreadsheet is a universal format anyone can open, sort, and filter.
Analyze API Data
Paste an API response and immediately slice, pivot, and chart the data in familiar spreadsheet tools.
Export Application Data
Turn config or database exports into a tidy table for review, backup, or reporting.
Bridge Teams
Give non-technical teammates data they can use without writing code or running scripts.
Automate Reporting
Feed JSON outputs into Excel-based reporting workflows and dashboards your org already runs.
Debug APIs
Inspect a response as a table to spot missing fields, bad types, and outliers at a glance.
Who Needs This Tool?

How to Convert JSON to Excel
Three steps in your browser — no install, no upload, no account.
Step 1
Paste or drop your JSON
Paste JSON into the editor or drop a .json file. The "Load Example" and "Format JSON" helpers are there if you want a starting point or need to tidy messy JSON.
Step 2
Convert in the browser
Click Convert to Excel and the JSON to Excel converter parses your data locally — no upload, no signup, no server queue. Preview the first 100 rows before you download.
Step 3
Download your .xlsx
Save a real OOXML .xlsx workbook that opens in Excel, Google Sheets, Apple Numbers, or LibreOffice — or copy the result as CSV in one click.

Frequently Asked Questions
Paste your JSON into the editor above or drop a .json file, click Convert to Excel, then download the .xlsx. The whole flow runs in your browser — no signup, no upload. You can also copy the result as CSV when a full spreadsheet is more than you need.
Excel's built-in Power Query can do it: go to Data → Get Data → From File → From JSON, then expand the records into columns. It works for one-off files but is cumbersome for nested arrays and not practical across many payloads. A dedicated JSON to Excel converter is usually faster and handles the flattening for you.
Yes. Nested objects are dot-flattened — {"user":{"name":"Alice"}} becomes a column named user.name. Arrays of objects inside a row are kept as a JSON string in the cell so no data is lost, and the column order follows the order fields first appear in your data.
No. Parsing, flattening, and the .xlsx write all happen in your browser — there is no network call, nothing stored, and nothing to auto-delete later. Some ranking tools say the conversion "runs in your browser" but still POST your JSON to a server with size caps and daily quotas; this one genuinely stays on your device.
The cap is 100 MB per file, with no daily quota and no signup — larger than Aspose's 2 MB free tier and ConversionTools' 10 MB / 5-conversions-per-day limit. Because everything runs in the browser, real-world speed depends on your device, and files at or below 100 MB convert smoothly.
Yes. Numbers stay numeric and work in formulas, booleans become TRUE/FALSE, and null becomes an empty cell. Once your JSON to Excel output is in a spreadsheet, you can compare two columns in Excel against another dataset and the types hold up.
Yes. The output is a standard OOXML .xlsx workbook, the default Excel format since 2007, and it opens cleanly in Google Sheets, Apple Numbers, and LibreOffice Calc. If you need to do more afterwards, that same .xlsx fits into the full set of Excel tools on this site without reformatting.
Some converters title their page ".xlsx" but actually ship an .xls (Excel XML) file — at least one ranking tool admits this in its own FAQ, citing "browser compatibility." This converter writes the file with the xlsx book type and the proper OOXML MIME, so the download is a true .xlsx, not a renamed .xls.
Three shapes all work: an array of objects (the common API response), a single object (flattened into one row), and a simple value array like [1,2,3] (each value becomes a row). Missing fields are handled by taking the union of all keys as columns; an object without a given field just gets an empty cell.
Yes — alongside the .xlsx download there is a one-click "copy as CSV" button, handy when you need to paste into another tool or load a database. If you regularly move data the other direction, you can also export Excel back to CSV in the same browser-based flow.
Arrays of simple values like ["admin","vip"] are joined with semicolons into one cell. Arrays of objects are kept as a JSON string inside the cell so no data is lost — you can pull them apart later with formulas or a script. If you then need to reconcile two Excel sheets, the cells come back in cleanly.
It is free with no signup, no account, and no usage caps — convert as many payloads as you need. The same no-login rule applies across the sibling tools, so you can convert CSV into Excel just as easily when your source is a delimited file instead of JSON.
