About TXT and XLSX

TXT (Plain Text) is unformatted text with no styling, fonts, or embedded objects — the most universally compatible format there is.

XLSX (Microsoft Excel Workbook (Office Open XML)) is Excel's modern XML-based format, supporting formulas, multiple sheets, charts, and conditional formatting.

What to expect: TXT carries little to no formatting of its own, so the XLSX output will start plain — you can add styling afterward in a compatible editor.
