What is a .SEAM file?
The most common data format on the web.
A .seam address is a URL handled by a Java web application built on the JBoss Seam framework. The server maps the request to a page and returns ordinary HTML to your browser. There is nothing to download or open locally. If you saved a .seam page from your browser, it is plain HTML; open it in any browser. The legacy label Sales report file is incorrect; .seam is a Seam framework web page, not a report format.

Frequently asked questions
Is my .SEAM file uploaded anywhere?
No. The file is opened directly from the copy you pick.
My .SEAM 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.
