How to convert TSV to XLSX

Sheetize TSV‑to‑XLSX Converter for .NET provides a simple yet powerful API for reading TSV (tab‑delimited) data and writing it to an Excel workbook while preserving column types, header rows, and cell styling. This is useful when you need to distribute data in a familiar spreadsheet format or integrate it into workflows that only accept XLSX files.

Main Features

Convert TSV to XLSX

Read any TSV file (tab‑delimited) and generate a macro‑free XLSX file, with optional data‑type inference and custom column formatting.

Preserve Formatting & Data Types

Detect numbers, dates, booleans and apply appropriate Excel styles; you can also supply a style template to keep a consistent look.

Streaming Support

Process huge TSV files row‑by‑row to keep memory usage low, perfect for batch conversions or web services.
