Parser Configurations

Flattening Deep Structures

Our recursion engine crawls deeply nested keys, flattening them into relational table rows. Choose dot separation (`person.name`) or slash paths, and easily index lists.

Google Sheets & Excel Specs

Exporting to regional Excel files? Semicolons are automatically selected to prevent column errors. UTF-8 BOM headers ensure special characters and accent marks open correctly.

Enterprise Sandbox Security

We understand compliance. No requests are ever logged or dispatched over the web. Run conversions completely offline; disconnect your internet and verify yourself.
