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.
XLSX
XLSX is the default spreadsheet format for Microsoft Excel since Office 2007, built on the Open XML standard and standardized by ISO. It stores worksheets, formulas, charts, pivot tables, and formatting in a compressed ZIP archive of XML files, making it more compact and corruption-resistant than the older XLS format. XLSX is supported by Google Sheets, LibreOffice Calc, Apple Numbers, and virtually every modern data tool.
