Format Details
TSV
TSV (Tab-Separated Values) is a plain-text tabular data format that uses tab characters as column delimiters and newlines to separate rows, making it similar to CSV but avoiding issues when data values contain commas. It is well-supported by spreadsheet applications, relational databases, and scripting languages, and is commonly used for data exports from bioinformatics databases, genome browsers, and text-processing pipelines.
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.
