About This Tool

Introduction

XLSX to CSV Converter turns Excel spreadsheets into clean CSV files in one click. Data analysts, developers and store owners often need CSV for databases, imports and scripts. Upload your XLSX or XLS file, pick the worksheet and delimiter, and download a properly formatted CSV.

How to Use

1. Drop an Excel file into the upload area, or click to browse.
2. Choose the worksheet and the delimiter your system needs: comma, semicolon, tab or pipe.
3. Click Convert to CSV and preview the first rows.
4. Download the CSV file or copy it to your clipboard.

Key Features

• Multi-sheet support: convert any worksheet from workbooks with many tabs.
• Four delimiters: comma, semicolon, tab and pipe for any import format.
• Live preview: check the first rows before downloading.
• Excel-compatible output: UTF-8 with BOM so Excel opens special characters correctly.
• 100 percent private: conversion runs in your browser, nothing is uploaded.

Why Choose Trencada

Desktop Excel can export CSV, but the delimiter options are buried and multi-sheet files are a hassle. Trencada gives you the worksheet picker, delimiter choice and preview in one clean screen, free and without signup.

FAQ

Which Excel formats are supported? XLSX and XLS files up to 25MB, plus CSV files if you want to change delimiters.
