PGM file (PGM) stores data in the PGM format. 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. 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. The result is a standard CSV file readable by any compatible application. 1converter handles PGM-to-CSV 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.
