How to convert MSG to JSON

  1. 1

    Choose your MSG files

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Start the conversion

    Press the convert button. Your browser converts the files in seconds.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

Feed email data from Microsoft Outlook into scripts, databases and analysis tools. Each message becomes an object with from, to, cc, date, subject, text, html and an attachments list (name, type, size).

What is MSG?

MSG is Microsoft Outlook’s single-message format. Dragging an email out of Outlook on Windows creates one. It can’t be opened on a Mac, phone or in webmail without conversion.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight structured data format used by virtually every web API and modern application.

Is it private?

Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.

Frequently asked questions

Is the msg to json converter free?

Yes. Convert 1 file a day without an account, or 5 files a day with a free account. Pro removes all daily limits.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple MSG files at once?

Yes. Select several MSG files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
