Understanding csv and wk1 file formats

CSV (Comma-Separated Values) is a widely used plain text format for storing tabular data, where each line represents a row and columns are separated by commas. It is supported by most spreadsheet and database applications.

WK1 is the file extension for Lotus 1-2-3 spreadsheet files, specifically for version 1. These files store spreadsheet data in a proprietary binary format, which was popular in the 1980s and 1990s but is now largely obsolete.

Why convert csv to wk1?

Converting CSV to WK1 may be necessary for compatibility with legacy systems or software that only supports Lotus 1-2-3 spreadsheets. This is common in organizations maintaining historical data or using older business applications.
