KEY to NUMBERSConverter — Fast & Free Online

The KEY file format stores data in the KEY format. Converting to NUMBERS produces a spreadsheet file that stores data in the NUMBERS format. This extracts structured tabular data from the document into an editable spreadsheet format. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. This makes NUMBERS the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
