The .HCL file extension is primarily associated with the HashiCorp Configuration Language, but it is also used for a HotDocs Clause Archive.
What is an HCL file?
A .HCL file usually contains configuration instructions written in the HashiCorp Configuration Language. Developers use this format with tools like Terraform and Vault to define cloud infrastructure. The language is designed to be readable by both humans and machines.
Alternatively, a .HCL file can be a HotDocs Clause Archive. The HotDocs software uses these files to store standard text clauses for automated document generation in legal and corporate environments.
How to open HCL files?
If your .HCL file is a HashiCorp configuration file, you can open it with any standard text editor. Popular choices include Visual Studio Code, Notepad++, or Sublime Text. Many text editors offer syntax highlighting plugins specifically for .HCL files.
If your file is a HotDocs Clause Archive, you need the HotDocs software installed on your computer to open the file and use the clauses properly.
Best practices and troubleshooting
Because .HCL files can serve entirely different purposes, the first step is to identify the file contents. If you open the file in a text editor and see plain text defining servers or networks, it is a HashiCorp file. If the file appears as unreadable data, it is likely a HotDocs Clause Archive.
Software and tools
For developer files, Terraform is the primary command-line tool used to execute .HCL configurations. For legal document automation, HotDocs is required to process the archive.
Summary
The viewer.online/hcl platform can analyze .HCL files to identify the exact format and creator software. It allows you to inspect the file structure, extract readable text, and check whether an online preview is available. Because .HCL has multiple possible meanings, we recommend using viewer.online/hcl to identify the actual format of your file. This tool is highly useful for identifying, inspecting, and understanding .HCL files without installing software or dealing with compatibility problems.
