Why
Why convert Excel to JSON?
Turn an Excel sheet into JSON for apps, websites and code. Each row becomes an object, with the first row as keys, and a workbook with several sheets becomes one object per sheet.

About the formats
What is Excel?
XLSX has been the Excel format since Office 2007. A workbook can hold many sheets, and keeps numbers, dates and formulas. ConvertOrino reads the values Excel saved for each cell, also from older XLS files and LibreOffice ODS files.
What is JSON?
JSON is the standard text format for data on the web. APIs, apps and configuration files use it. A table in JSON is usually a list of objects, one per row, with the column names as keys.
Questions
Questions and answers
Is it safe to convert my files here?
Yes. ConvertOrino converts your files with code that runs in your own browser. Nothing is uploaded to a server, nobody else can see your files, and they are gone as soon as you close the page.
Is the Excel to JSON tool free?
Yes, completely free. There is no sign up, no watermark and no limit on the number of files.
Is there a file size limit?
There is no fixed limit, because your own device does the work. Very large files are limited by the memory of your device. Phones handle files of a few hundred megabytes, computers handle much more.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any modern browser, including Safari, Chrome, Edge and Firefox, on phones, tablets and computers. Nothing needs to be installed.
Does it work offline?
Yes. Once the page has loaded, the conversion works without an internet connection, which also proves that your files are not sent anywhere.
