What is a FANUC LS file?

An LS file is a human readable ASCII export of FANUC robot program data. It is typically produced via RoboGuide or controller export workflows and is used for review and controlled edits.

Q: Does this convert TP to KAREL?

What it does

This workflow reads LS text and extracts structured robot data for review, comparison, and controlled editing. It does not require TP conversion.

Typical exports

Registers and position registers
Frames, tools, payloads, and I/O labels
Program structure, comments, and line level diffs
Engineering packs for Excel, PDF, DXF, and 3D scenes

Example LS snippet

The goal is clean, predictable extraction without TP conversion. LS stays LS.

FAQ

Does this convert TP to KAREL?

No. This focuses on LS files and robot data extraction, review, and controlled edits.

Do standard FANUC backups include LS files?

Typically no. Standard backups generally do not include LS unless you explicitly exported programs to LS or generated text dumps. This tool expects LS exports as input.

What do I need as input?

Exported LS files. These can be produced from RoboGuide, from a controller export workflow, or via a controlled dump utility. The tool reads the LS text structure and builds tables from it.
