## About

## What it does
CSV to Excel Converter turns a CSV file or CSV URL into an XLSX spreadsheet. Send a file upload to get a binary XLSX download, or request a signed link when you want the converted workbook stored and fetched later.

Use the `/file/download` and `/url/download` endpoints when you need the converted spreadsheet immediately in your app or backend workflow. Use the `/file/link` and `/url/link` endpoints when you prefer a URI response that points to the generated XLSX file. The request body accepts either `file` for an uploaded CSV or `url` for a remote CSV source, and the download endpoints also accept an optional `output` query value for the filename.

This is a practical fit for internal admin tools, import pipelines, reporting jobs, and any workflow that receives CSV exports from users or third-party systems but needs an Excel workbook for review or handoff. The API keeps the contract simple: provide the CSV source, then receive either the XLSX binary stream or a signed `data` link back.
