Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
What this Lucaden tool does
Papa Parse handles quoted fields, embedded delimiters, and line breaks before ExcelJS writes a worksheet. The generated workbook includes a frozen, bold header row and sensible column widths.

Questions
About this tool
Can CSV contain multiple sheets?
No. One CSV becomes one worksheet because CSV has no multi-sheet structure.
Are numbers typed as numbers?
Basic booleans and numeric values are detected where conversion is unambiguous.
