Format Details
CSV
CSV (Comma-Separated Values) is a plain-text tabular data format that uses commas to delimit column values and line breaks to separate rows. It is one of the most universally supported data interchange formats, readable by any spreadsheet application, database, or programming language. CSV is ideal for exporting and importing data between different systems due to its simplicity, human readability, and near-universal compatibility.
FWF
FWF (Fixed-Width Format) is a plain-text data format where each column occupies a predetermined number of character positions in every row, with no delimiter characters between fields. It originated on mainframes and is still common in government data releases, financial industry feeds, and legacy enterprise system exports. FWF files require a separate schema or data dictionary to correctly parse the column boundaries, making them less self-describing than CSV.
