(Delphi ActiveX) XLSX Spreadsheet in AI Query

See more AI Examples

This example shows how to convert a .xlsx spreadsheet to CSV text for input in an AI query. Currently, most AIs can't handle Excel file inputs directly. If the spreadsheet is small, you can convert it to CSV text and use it as a text input.

Note: This example requires Chilkat v11.3.0 or greater.
