Data portability is the primary motivation. CSV files open in every programming language, database import tool, data analysis platform, and text editor. Python's pandas, R's read.csv, SQL LOAD DATA, and countless other tools consume CSV natively. XLSX requires specialized libraries (openpyxl, xlrd) that add complexity and dependencies. For data pipeline integration, CSV is the universal interchange format.

File size and simplicity matter for data processing. An XLSX file stores formatting, styles, formulas, charts, and XML metadata alongside the actual data — overhead that inflates file size and adds complexity. CSV strips away everything except the raw values, producing files 60-90% smaller than the original XLSX. This makes a meaningful difference when processing thousands of files or transferring data over limited bandwidth.

Database import workflows demand CSV. Importing data into PostgreSQL, MySQL, SQLite, BigQuery, Snowflake, and other databases is straightforward with CSV but complicated with XLSX. Most database import utilities expect CSV or TSV format. Converting XLSX to CSV before import eliminates parsing errors, encoding issues, and the need for Excel-specific import plugins.

LibreOffice evaluates all formulas in the XLSX file before export, replacing formula cells with their computed values. This means the CSV contains actual numbers and text, not Excel formula syntax. Cell references, VLOOKUP, SUMIF, and other formula types are fully resolved.

Multi-sheet workbooks produce one CSV file per worksheet when batch processing is enabled, or a single CSV from the active (first) sheet by default. Sheet names can be preserved in the output filenames. Empty rows and columns at the edges of data ranges are trimmed to produce clean CSV output without trailing delimiters.

Character encoding defaults to UTF-8 with BOM (Byte Order Mark) for compatibility with Excel's CSV import. Fields containing commas, quotes, or newlines are automatically quoted per RFC 4180. Date values are exported in ISO 8601 format (YYYY-MM-DD) by default, avoiding the ambiguity of locale-dependent date formats like MM/DD/YYYY vs DD/MM/YYYY.

No — formulas are evaluated and replaced with their computed values. If a cell contains =SUM(A1:A10) with a result of 500, the CSV will contain 500. CSV is a plain-text data format that cannot represent formulas. If you need formulas, keep the XLSX file.

All formatting is lost. CSV stores only raw data values — no fonts, colors, borders, conditional formatting, or cell styles. The data content is preserved exactly, but visual formatting cannot be represented in plain text.

Dates are exported in ISO 8601 format (YYYY-MM-DD) by default, which is unambiguous and universally parseable. This avoids confusion between American (MM/DD) and European (DD/MM) date formats that plague locale-dependent CSV exports.

Merged cells are unmerged during conversion. The original value is placed in the top-left cell of the merged range, and the remaining cells are left empty. This preserves the data but changes the visual structure.

By default, the first (active) worksheet is converted. Multi-sheet export produces separate CSV files for each worksheet. Sheet names are used in the output filenames to distinguish them.

UTF-8 with BOM by default, which ensures proper handling of international characters (accented letters, CJK text, symbols) while maintaining compatibility with Excel's CSV import. Pure UTF-8 without BOM is also available.

The underlying numeric value is exported, not the display format. A cell showing $1,234.56 exports as 1234.56. A cell showing 75% exports as 0.75 (the actual stored value). This ensures the data is machine-readable.

The default delimiter is a comma, per the CSV standard. Fields containing commas are properly quoted. You can specify a different delimiter (semicolon, tab, pipe) if your downstream tool requires it.
