What is a .LED file?
The most common data format on the web.
An LED file is a proprietary behavior sequence used by classic Sony AIBO robots (ERS-series, 1999-2006) to control LEDs on the robot's chest, face, ears, and tail. There is no modern software to open these files on a PC. Windows Media Player cannot open LED files despite appearing in some file association databases.

Frequently asked questions
Is my .LED file uploaded anywhere?
No. The file is opened directly from the copy you pick.
My .LED file is invalid. Can you fix it?
We show the exact line and column of the first error. For common problems like comments, trailing commas, single quotes or Python-style True/False/None, click Try to repair and download the fixed file.
How large can the file be?
Up to 50 MB. The tree only builds the branches you open, so even multi-megabyte files stay responsive.
What is JSONPath?
A path like $.orders[3].customer.email that points to one value inside the data. Click any node to see its path and copy it for code, jq or your API docs.
Can I see my data as a table?
Yes. Any array of objects can be shown in the Table view and downloaded as CSV.
