TSV vs XLSX

TSV (TSV) uses MIME type application/tsv, whereas XLSX (XLSX) uses application/xlsx. Each format optimizes for different trade-offs in file size, fidelity, and software compatibility.

Yes. KaijuConverter uses tuned encoding profiles to preserve maximum visual, audio, or document fidelity when converting between TSV and XLSX.

TSV (TSV (Tab-Separated Values)) is a spreadsheet format used to store tabular data in rows and columns, typically with multiple sheets per workbook, cell formatting, formulas, and optional charts. It is part of the spreadsheets & data family and is the native format of a specific spreadsheet application.

XLSX is the default spreadsheet format for Microsoft Excel since 2007. It is based on the Office Open XML standard and supports multiple sheets, formulas, charts, pivot tables, and conditional formatting.

Excel, Google Sheets, LibreOffice Calc, and Apple Numbers handle most TSV files with high fidelity. For simple one-off viewing, Google Sheets and the Office web apps open TSV in the browser without installing anything. Convert to XLSX or CSV first if your target tool is strict about formats.

XLSX files open in Microsoft Excel, Google Sheets (free), LibreOffice Calc (free), and Apple Numbers. Online viewers like OneDrive and Google Drive also support them.

Upload the TSV to KaijuConverter and pick XLSX, CSV, ODS, TSV, or PDF. Our LibreOffice-based pipeline reads the sheet data, preserves cell types (numbers, dates, strings), and writes a clean target file. Multi-sheet workbooks come back as a single multi-sheet export or a ZIP of per-sheet CSVs depending on target.

When converting between spreadsheet formats that support formulas (XLSX, ODS), formulas transfer with function-name translation. When converting to CSV, formulas resolve to their cached evaluated value (open the source in Excel once to force evaluation if you suspect stale cache).
