Frequently asked questions

Everything you need to know about converting CSV files online.

Is CSVShift really free to use?

Yes, completely free. All 59 CSV conversion tools are available with no limits, no watermarks, and no account required. CSVShift is funded by non-intrusive display advertising.

Is my data safe when I convert CSV files online?

Absolutely. All conversions run directly in your browser using JavaScript. Your CSV files are never uploaded to any server. Open the Network inspector while converting — you will see zero outbound data requests.

Are there file size limits?

No limits imposed by CSVShift. Practical limits depend on your browser's available memory — most modern browsers handle CSV files up to several hundred MB without issues.

What makes CSVShift different from other CSV converters?

Three things: 1) Privacy — all conversions run in your browser, zero uploads. 2) Real binary output — Parquet, Avro, DBF, SQLite and DOCX are genuine binary files, not text files renamed. 3) Code generators — the Analytics & Code tools generate ready-to-run pandas, R, Colab, Power BI and Tableau code from your actual column names.

How do I convert a CSV file to Excel?

Use the CSV to Excel tool above. Drop or select your .csv file, click Convert, and download the .xlsx file instantly. No Excel installation required. Bold headers, auto-sized columns and number type detection are applied automatically.

How do I load a CSV into pandas?

Use the CSV → pandas tool. Upload your CSV and choose a script mode — Basic (read_csv + describe), Analysis (stats + correlation + plots) or Cleaning (strip, coerce, save). The generated Python script uses your actual column names and inferred dtypes. Download as .py and run without modification.
