How to Convert Excel to CSV Online — Free Guide (2026)
Excel files are the standard for business data, but databases, APIs, and data processing tools typically require CSV. Converting Excel to CSV strips out formatting and produces clean, universally compatible tabular data.
ToolHQ converts Excel (XLSX, XLS) to CSV in your browser with no server upload, no registration required.
How to Convert Excel to CSV on ToolHQ
Converting Excel to CSV takes three steps:
**Step 1:** Go to toolhq.app/tools/excel-to-csv.
**Step 2:** Upload your Excel file (.xlsx or .xls).
**Step 3:** If the workbook has multiple sheets, select which sheet to convert. Click 'Convert to CSV' and download.
Formulas are evaluated and their current values are exported as CSV data. Formatting, charts, and images are discarded — only the cell values are preserved.
What Happens to Excel Features During Conversion
Excel to CSV conversion strips most Excel-specific features:
**Preserved:** Cell values (text, numbers, dates), basic structure (rows and columns), special characters with UTF-8 encoding.
**Discarded:** Formulas (replaced by their calculated values), formatting (colors, fonts, borders), charts and images, multiple sheets (only one sheet per CSV), merged cells (expanded to individual cells), comments and notes.
If you need to preserve multiple sheets, convert each sheet separately to individual CSV files.
Excel to CSV for Database Import
The most common use case for Excel to CSV is database import. Most databases support CSV import directly:
**MySQL:** LOAD DATA INFILE or the import wizard in MySQL Workbench.
**PostgreSQL:** COPY command or pgAdmin's import tool.
**SQLite:** .import command in the SQLite CLI.
**Airtable, Notion, Monday.com:** All support CSV import for bulk data entry.
Before importing, ensure your CSV headers match your database column names exactly, and that data types are compatible.
Conclusion
Excel to CSV conversion produces clean, universally compatible data files for databases, APIs, and data processing. ToolHQ converts Excel to CSV for free in your browser at toolhq.app/tools/excel-to-csv.
