How this shelf works
About data tools
Data tools handle the small, repeatable jobs that show up between real work: csv, tsv, tables. They are built as focused utilities, so each page does one job without asking you to create an account or install software.
Open a tool, add your input, adjust the settings, and download the result. Processing happens in the browser using the platform APIs available for that file type. Files are not uploaded to a server, so the tool keeps working offline once the page has loaded.

Data tool questions
Are data tools free?
Yes. Every data tool on utils.sbs is free, requires no account, and has no per-file or per-use charge.
Are my files uploaded when I use a data tool?
No. The tools are designed to process input in the browser whenever the platform API allows it. Files are not uploaded to a server for processing.
Do I need to install anything to use these tools?
No. Everything runs in a modern web browser. Open a tool page, use the workspace, and download the result.
How do I choose the right data tool?
Each tool page describes what it does, its input and output formats, the engine it uses, and its limitations. Start with the description that matches your job, then open the tool page for the workspace and step-by-step guide.
