Frequently asked questions

Does it handle different delimiters or encodings?

The converter expects a standard comma-separated CSV file. If your file uses semicolons, tabs, or an unusual text encoding as its separator, values can land in the wrong columns. Re-saving the file as a plain comma-delimited CSV before uploading usually fixes this.

Will number and date formatting carry over?

Values are written into spreadsheet cells as plain text or numbers based on what's in the CSV. You may need to reapply specific display formats (currency symbols, leading zeros, or date styles) once the file opens in Excel.
