Safety guidance (not a guarantee)

Source code is plain text and doesn't execute on its own — it has to be compiled or run by a specific tool, which is where any real risk would occur.

Frequently asked questions

What is a .tsv file?

Like CSV, but values are separated by tab characters instead of commas — useful when data itself may contain commas.

Can I edit a .tsv file?

Yes — .tsv files are commonly editable with software such as Microsoft Excel.

Does having a .tsv extension mean the file is safe?

No single extension can guarantee that. Source code is plain text and doesn't execute on its own — it has to be compiled or run by a specific tool, which is where any real risk would occur. Always consider where the file came from, not just its name.
