If you write documentation on GitHub, GitLab, or use Obsidian, you deal with Markdown tables. And you know they are a pain to write by hand.
The Hack
Aligning pipes (|), escaping special characters, and maintaining readability in plain text is tedious. The usual shortcut is to copy data from Excel or a CSV file, paste it into a free online converter, and grab the markdown output.
But here is the massive problem: where does that pasted data go?
Most of these tools process data on a backend server. If you are pasting internal company analytics, financial data, or API schemas, you are transmitting sensitive information to a third party. If your company requires you to sign an NDA, using these online converters is a direct violation of data privacy policies.
