XLSX Conversion Errors - Sheets, Formulas, and Export Fixes

Fix XLSX conversion issues including missing sheets, formula loss, formatting changes, and CSV export problems.

Why did formulas disappear when converting XLSX?

Many target formats, especially CSV and PDF, preserve results rather than live spreadsheet formulas. CSV in particular cannot store formulas as spreadsheet behavior.

Why is only one sheet present after conversion?

Some output formats only support a single sheet or a flattened representation. CSV is the most common example because it cannot carry multiple worksheets.

Why did my formatting change?

Cell colors, merged cells, widths, and styles are layout features specific to spreadsheet formats. Simpler output formats may keep values but not visual formatting.

Why do exported numbers look different?

Date parsing, locale settings, decimal separators, and formula evaluation can all change how numbers appear after export.

What format is best for editable spreadsheet sharing?

XLSX is usually the best default when you need to preserve workbook structure, sheets, and most spreadsheet behavior.

What format is best for raw data exchange?

CSV is best for simple tabular data exchange when you do not need formatting or workbook features.
