How to use
- Upload CSV files (up to 20 at once), or paste spreadsheet text into the box. A sample is prefilled so you can download right away.
- Leave the delimiter on auto detect, or pick comma, semicolon, tab or pipe. If a Chinese file looks garbled, switch encoding to GBK and re-upload.
- With several files, choose one sheet per file or merge them all (repeated headers are skipped when merging).
- Toggle first row as header (bold + frozen), auto filter, auto column width and number detection. IDs with leading zeros stay text so nothing is lost.
- Click Download XLSX. The file opens in Excel, WPS and LibreOffice, and every cell stays selectable and copyable.
Current limits: 50000 rows and 500 columns per sheet.
