Univert

The universal file converter — a single CLI that converts between 27 file formats, preferring pure-Rust libraries and shelling out only for tools with no Rust equivalent (LilyPond, OpenSCAD, FFmpeg, FluidSynth).

For the desktop version, see univert-gui.

Install

cargo install univert

Usage

univert <input-file> <output-file> [OPTIONS]

Flags:

• -f, --force — overwrite existing output
• -l, --list — print every supported conversion and exit
• -s, --split — split source file into several target files (csv/tsv → json)
• -h, --help, -V, --version

Examples:

univert notes.json notes.yaml
univert contacts.vcf contacts.json
univert logo.svg logo.png
univert song.abc song.midi          # requires lilypond + abc2ly
univert part.scad part.stl          # requires openscad
univert track.wav track.aac         # requires ffmpeg

Supported conversions

Pure-Rust (no external tool required):

Shell-out to external tools when available:

Run univert --list for the complete registry.

Library

use std::path::Path;

let opts = univert::Options { force: true, split: false };
univert::convert(Path::new("in.csv"), Path::new("out.json"), &opts)?;
# Ok::<(), univert::Error>(())
