Convert CSV to Excel API

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.
