Frequently asked questions

What is CSV Studio for VS Code?

CSV Studio is a free Visual Studio Code extension that opens CSV and TSV files in a fast, spreadsheet-style grid with sorting, filtering, and column tools — without leaving the editor.

Does CSV Studio handle large CSV files?

Yes. CSV Studio renders tabular data in a virtualized grid so you can browse, sort, and filter large delimited files locally inside VS Code without exporting them to another app.

Is CSV Studio free and offline?

Yes. CSV Studio is free on the Visual Studio Marketplace and Open VSX, and it parses files locally on your machine, so your data never leaves your computer.

How do I install CSV Studio in VS Code?

Open the Extensions view in Visual Studio Code, search for "CSV Studio", and click Install — or get it from the Visual Studio Marketplace or Open VSX. No sign-in or account is required.

Why edit CSV files inside VS Code instead of a spreadsheet app?

Editing CSV and TSV files in VS Code keeps tabular data next to the code, scripts, and docs that use it, so you can review and adjust datasets without switching tools or breaking your workflow.
