CSV to XLSX converter

CSV is a widely used data format. This skill turns CSV input into styled XLSX workbooks.

Workflow

Read the CSV input and detect the delimiter.
Create a workbook and write the header row in bold.
Freeze the top pane and auto-size the columns.
Save the workbook next to the source file.

For the delimiter you can use a comma, or a semicolon, or a tab, or any single character the source uses.

The output keeps one sheet per input file and uses the file name as the sheet name.
