What it is and what it does
xlsx2csv is a lightweight command-line tool and Python library that converts Microsoft Excel XLSX files to comma-separated values (CSV) format. It parses the underlying XML structure of XLSX files using an Expat SAX parser, supporting both single-sheet and multi-sheet conversion with options to filter sheets by name or pattern, customize delimiters and line terminators, override date and float formatting, and preserve hyperlinks.
You can use it as a standalone script from the command line, process entire directories of XLSX files in batch, or import it as a Python module within your own code. It requires no external dependencies beyond the Python standard library, making deployment straightforward across many Python versions.
Use it for
- Batch convert a directory of XLSX files to CSV for data pipeline ingestion or legacy system compatibility.
- Extract specific sheets from multi-sheet workbooks while filtering by name patterns to automate report generation.
- Programmatically convert XLSX data to CSV within Python scripts for ETL workflows or data cleaning tasks.
- Customize CSV output encoding, delimiters, and date formats to match downstream system requirements.
- Convert XLSX files from STDIN or write CSV output to STDOUT for integration into shell pipelines.
