Excel to CSV

POST /api/excel-to-csv

Convert an Excel sheet to CSV. Pick a specific sheet by name or index. Cell values are stringified; formulas are evaluated to their cached result.

Reads an Excel workbook (.xlsx or legacy .xls) and returns one sheet as CSV. Options: - `sheet`: pick a sheet by 0-based index (`0`, `1`, …) or by name (`Summary`, `Data`). Default is the first sheet. - `delimiter`: output separator (default `,`; pass `\t` for TSV). Cell values are stringified using their displayed format; formulas are evaluated to their cached result (Excel saves this when the file is closed).

Inputs

Name	Type	Default	Description
workbook*	file	—	Excel workbook bytes (XLSX, XLSB, XLS, or ODS).
sheet	string	—	Sheet name (case-sensitive) or 1-indexed sheet number as a string. Defaults to the first sheet.
delimiter	string	","	Field delimiter (default `,`).
rawValues	boolean	false	When true, return raw cell values; when false (default), dates are formatted as ISO strings.

Response

Modes: json. Cache: yes (24h TTL).
