What is a .CSPROJ file?
The most common data format on the web.
A CSPROJ file is a C# project file, an XML file created by Microsoft that tells the build system how to compile one C# project: which source files to include, which NuGet packages to use, and which .NET version to target. It contains no source code. Open it in Visual Studio, VS Code with the C# Dev Kit, or JetBrains Rider, or build from a terminal with the free .NET SDK (dotnet build). To just read it, any text editor works.

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