What CSV to XLSX Converter takes and returns
You give it
fileBase64filefilenametext, for example revenue.csv
A three-line CSV: the header name, email, plan; a row for Acme Dental; and a row whose name cell starts with =HYPERLINK(...).
You get back
converted-data.xlsx with one sheet named Imported data: header row frozen, autofilter on every column, and the =HYPERLINK cell stored as plain text, ready to download.
How the 3-step flow works
A credential-free conversion service that parses CSV bytes, creates a single-sheet XLSX workbook with a header row, frozen header, and autofilter, escapes leading formula-like text characters, and returns an allowlisted downloadable artifact. It uses bounded local computation and no model call.
Ops and finance teams use it to hand clients and managers a spreadsheet that opens clean in Excel: the header row stays pinned while they scroll, every column filters from the first click, and a cell that starts with =, +, - or @ is escaped so an exported CRM or ad report can never run a formula on the reader's machine. With no model in the flow, a conversion spends no model credit.
