What is a .GRAPHML file?

The most common data format on the web.

A GRAPHML file stores a mathematical graph (a set of nodes and edges) in plain XML. Open it with Gephi (free) or yEd Graph Editor (free) to visualize the network. It cannot be opened in Excel. The file is plain XML and cannot execute code, so it is safe to open.

Frequently asked questions

Is my .GRAPHML file uploaded anywhere?

No. The file is opened directly from the copy you pick.

My .GRAPHML 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.
