About makiconvertpro

makiconvertpro is a free tool that turns CSV files into Excel spreadsheets.

Most online converters upload your file to a server. makiconvertpro does the work inside your browser instead, so customer lists, invoices and exports stay on your device.

What it does

• Reads CSV, TSV and plain-text table files
• Detects the separator and text encoding
• Creates a standard .xlsx workbook with a styled header row
• Keeps leading zeros and long numbers safe
