The formats
JSON and Excel at a glance
What is a JSON file?
JSON is a text format for structured data made of objects, arrays, strings, numbers, and true or false values. It's the standard format for web APIs and config files, and every programming language can read it. Nested data doesn't map directly onto a flat table. It opens in any text editor, VS Code, browsers, and every programming language.
What is an Excel file?
XLSX is the workbook format Microsoft Excel has used since 2007. A workbook can hold several sheets with formulas, formatting, charts, and filters, and it's the standard way spreadsheets are shared at work. It opens in Microsoft Excel, Google Sheets, Apple Numbers, LibreOffice Calc, and WPS Office.
Good to know
What changes when you convert JSON to Excel
- Each object in an array becomes a row. Nested objects are flattened into columns like address.city, and lists are written as JSON text.
- Numbers become real Excel numbers, so formulas and sorting work on them. Everything else is stored as text.
- Very large files, in the hundreds of megabytes, may be slow, and the preview shows only the beginning.
FAQ
Questions, answered
Is this JSON to Excel converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with open-source CSV, JSON, YAML, XML, and Excel libraries, so your files never leave your device. Once the page has loaded, it even works offline.
Can I paste JSON instead of uploading a file?
Yes. Paste JSON text onto the page and it's converted the same way. Nothing you paste leaves your browser.
Can I convert several JSON files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each Excel file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes. It works in Chrome, Edge, Firefox, and Safari, on computers and phones.
What can open an Excel file?
Microsoft Excel, Google Sheets, Apple Numbers, LibreOffice Calc, and WPS Office.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle files of a few hundred megabytes.
