Overview

Excel → CSV is built to solve the conversion between the Tab-separated text (TSV format) that spreadsheet software — Excel, WPS, Google Sheets — places on the clipboard and standard CSV. It automatically detects the pasted TSV and produces a CSV output that conforms to RFC 4180, avoiding field misalignment caused by commas or double quotes.

How to Use This Tool

Step 1 — in Excel, WPS Spreadsheet or Google Sheets, select the cells you want to convert and press Ctrl+C (or ⌘+C on Mac). Step 2 — come back to the tool, click the left input area and press Ctrl+V; the Tab-separated content is converted to standard CSV automatically. Step 3 — or click "Sample" to see how it works. Step 4 — the right panel shows the CSV, which can be copied to the clipboard or downloaded as a .csv file for database imports, script processing or sharing.

Common Use Cases

Finance teams convert Excel reports to CSV for uploading to an ERP; operations teams copy sales details from spreadsheets to analytics tools that require CSV; developers convert test data quickly when writing seed scripts; data engineers copy tables from Google Sheets for Python / Pandas; unify format across teams before sharing data files.

Technical Details

When pasting from Excel, the system actually places a text/plain TSV on the clipboard. The tool parses it with \t as the column separator. The CSV output follows RFC 4180 — fields containing commas, double quotes or newlines are wrapped in double quotes. Newlines are normalised to CRLF. Complex table structures with rich text, merged cells or formulas are not handled; for full .xlsx support use a dedicated Excel converter.

Privacy & Security

Pasted content is converted locally in your browser and is not uploaded, making it safe to use with financial, sales or HR tables.
