Frequently asked questions
Is Excel to JSON free to use?
Yes. Excel to JSON is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Excel to JSON upload your Excel file to a server?
No. Excel to JSON processes your Excel file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Excel to JSON.
Do I need to install anything to use Excel to JSON?
No installation is needed. Excel to JSON runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Will Excel to JSON keep the original quality?
Excel to JSON preserves the source content faithfully where JSON supports it. Where the two formats differ, the tool favours visual fidelity over the smallest possible output.
What happens to your Excel file when I close the tab?
It is discarded. Excel to JSON keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
