Can I convert password-protected PST files?▼
Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.
Can I convert multiple PST files at once?▼
Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.

JSON Data offers human-readable, language-independent with native JavaScript parsing. It's widely used for REST APIs, configuration files, web data exchange and NoSQL databases, making it an excellent choice for most data needs.
Will my PST file be deleted after conversion?▼
