About FileMint
FileMint (also known as TheFileMint) was built with one simple mission — to make file conversion fast, free, and frustration-free for everyone.
Why We Built FileMint
We got tired of file converters that were clunky, ad-ridden, or required you to create an account just to convert a simple spreadsheet. FileMint was born from the frustration of not having a clean, reliable, and truly free tool for everyday file conversion tasks.
Whether you're a developer converting JSON to Excel for a client report, a data analyst transforming CSV files, or anyone in between — FileMint (TheFileMint) is designed to get out of your way and let you focus on your work.
We support an ever-growing list of formats: JSON, Excel (XLSX), CSV, XML, YAML, and more. Every conversion happens securely, your files are never stored, and you never need to sign up to get started.
What We Stand For
The principles that guide every decision at FileMint.
Speed First
We believe your time is valuable. FileMint processes conversions in seconds, not minutes – no waiting, no queuing.
Privacy by Design
Your files are processed in memory and deleted immediately after conversion. We never store, read, or share your data.
Free for Everyone
Core conversions on FileMint are and will always remain free. We believe great tools should be accessible to all.
Built for the Web
No downloads, no installs. FileMint runs entirely in your browser and via our REST API – from anywhere, on any device.
