About the Excel to JSON Converter
Need to turn a XLSX file into JSON? This free converter changes XLSX spreadsheets into JSON in a few seconds, right in your browser. People usually convert because XLSX needs a spreadsheet app and is awkward to load into databases or code, while JSON gives you structured JSON. JSON files open in every programming language, VS Code, Postman, browsers and databases.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your spreadsheets are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: every sheet in the workbook is converted; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact; the first row is used as column names, which you can switch off.
How to use the Excel to JSON Converter
- Click "Choose files" or drag your XLSX spreadsheets onto the box. You can add several at once.
- Choose whether the first row holds column names and whether to convert all sheets or only the first.
- Press "Convert to JSON". The conversion runs on your device and shows its progress.
- Download each JSON file, or use "Download all (ZIP)" when you converted several.
- Open the result in every programming language or VS Code to check it; your original XLSX is never changed.
Tips & benchmarks
- The JSON is pretty-printed with two-space indentation and numbers and booleans keep their types.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the JSON to a website or government portal.
Frequently asked questions
How do I convert XLSX to JSON?
Click "Choose files", select your XLSX spreadsheets, adjust the options if you want, and press "Convert to JSON". The JSON downloads immediately; with several files you can download everything as one ZIP.
Is this XLSX to JSON converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your spreadsheets never leave your phone or computer and nothing is stored on News Appite's servers.
Are formulas, formatting and all sheets kept?
Every sheet is converted (or only the first, if you choose). Formulas are exported as their current values, and cell colours and fonts are not carried over because formats such as CSV, JSON and SQL cannot store them.
Can I convert several XLSX files at once?
Yes. Add as many XLSX files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between XLSX and JSON?
XLSX (Microsoft Excel Workbook (Office Open XML)) is a spreadsheet workbook best suited to working with data in Excel, Google Sheets and accounting or GST software. JSON (JavaScript Object Notation) is a structured data (text) best suited to APIs, web and mobile apps, configuration and MongoDB or Firebase data.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
Can I convert Excel to JSON offline?
The conversion itself runs on your device and nothing is uploaded. You only need an internet connection to open the page and, the first time, to download the conversion engine.
