CSV to KEYConverter — Fast & Free Online
The CSV to KEY converter runs without Java, Flash, or browser plugins. CSV (CSV (Comma-Separated Values)) is a simple text format for tabular data.

How CSV to KEY Conversion Works
Comma-Separated Values (CSV) stores tabular data as plain text with one row per line and field values delimited by commas, readable by any spreadsheet or database tool. KEY file (KEY) stores data in the KEY format. This converts the tabular data into a fixed-layout document suitable for printing or sharing. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard KEY file readable by any compatible application. 1converter handles CSV-to-KEY conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
