GEEDITOR / CSV → XLSX
About this conversion · CSV → XLSX
Move table values from CSV into XLSX for further work in another tool. Treat the result as a data transfer, not a workbook backup: formatting, charts and calculation logic need separate attention.
CSV values are read as text here. For example, 0012 stays a text value in the converter, but spreadsheet software can reinterpret it when you open the result. Import identifier columns as text and compare them with the original.
CSV input must use commas; TSV input must use tabs. Quote a field containing a delimiter or line break, and double embedded quotes. There is no delimiter picker or automatic semicolon conversion; export a correctly delimited file first.
XLSX, ODS and FODS outputs can contain multiple source sheets, but only supported cell values and sheet names are rebuilt. They do not preserve formulas as executable formulas, charts, macros or workbook formatting.
How to convert
- Click “Choose files” and select the original CSV file. Start with one file when comparing settings.
- Check that the output selector shows XLSX. The instructions here describe this choice; changing the output can change which settings apply.
- Click “Convert files”, then save the result from its file row. “Download all” puts completed files into a ZIP; it does not combine their contents.
- Open the XLSX result and compare row counts, headers, empty cells, dates and identifiers with the CSV source. Preserve codes such as 00123 as text in the receiving application; do not assume its automatic type detection is correct.
