About Excel to CSV Converter
Excel to CSV converts an Excel workbook (.xlsx or .xls) into a plain comma-separated file you can import into databases, CRMs, and legacy systems that reject Excel uploads.
What is Excel → CSV? CSV is a text table: one header row, then data rows separated by commas (or your locale’s delimiter). XLSX is a zip of XML sheets with formatting, formulas, and multiple tabs. CSV keeps values — not Excel formulas, charts, or macros.
How to convert Excel to CSV on FileToolsHub: upload the workbook, wait for the first sheet to export, download the .csv. Put the sheet you need first before uploading. Prefer UTF-8 when your importer supports it so names and accents stay intact.
XLS vs XLSX vs CSV: .xls is the older binary Excel format; .xlsx is modern Open XML; CSV is universal plain text. Use CSV to Excel when a double-clicked CSV opens as one messy column. Use Excel to JSON when APIs need row objects instead of flat files.
Privacy: the file is processed for conversion and removed from temporary storage afterward. Related tools: CSV to Excel, Excel to JSON, JSON to Excel, CSV to JSON. Spreadsheet hub: /spreadsheet. Tool: /tool/excel-to-csv.

Excel to CSV FAQ
Which sheet becomes the CSV?
The first worksheet in the workbook. Move the sheet you need to the front before uploading.
What about UTF-8 encoding?
CSV is plain text. Prefer UTF-8 when your importer supports it so accents and non-Latin names stay correct. If Excel opens garbled text, import via Data → From Text/CSV and pick UTF-8.
XLS vs XLSX vs CSV — which should I use?
Use XLSX when you need Excel formatting and multiple sheets. Use CSV when a system only accepts flat text imports. FileToolsHub Excel to CSV bridges XLSX/XLS into CSV for those importers.
Are formulas preserved?
No. CSV stores computed values, not Excel formulas, charts, or macros.
Which sheet is converted?
The first sheet in the workbook is converted. Move the sheet you need to the front first.
Are formulas included?
Exported values reflect computed results, not formulas. Charts and macros are not included in CSV.
Why use CSV instead of Excel?
Many CRMs, databases, and importers only accept CSV. Excel to CSV gives them a flat text table without requiring Excel on the receiving side.
Is Excel to CSV free?
Yes. Excel to CSV on FileToolsHub is free for everyday use with no account required for standard jobs.
