PSV (Pipe-Separated Values) is a simple, flat text format using pipe characters to separate data columns, while Texinfo is a structured documentation markup language designed for creating comprehensive technical documentation. The conversion process involves parsing the pipe-delimited data and transforming it into Texinfo's more complex markup structure, which supports advanced formatting, cross-referencing, and semantic document organization.

Users convert from PSV to Texinfo primarily to transform raw tabular data into professionally formatted technical documentation. Texinfo allows for creating comprehensive manuals, software documentation, and reference materials with advanced formatting capabilities that are not possible in the simple PSV format. This conversion is particularly useful for academic, technical, and software documentation projects that require structured, readable output.

Common conversion scenarios include transforming research data into academic documentation, converting software API reference tables into comprehensive user manuals, creating technical documentation for open-source projects, preparing scientific research findings for publication, and generating structured reference materials from raw data sources.

The conversion from PSV to Texinfo typically maintains the original data's integrity while significantly improving its presentation and readability. Some minor formatting adjustments may occur, but the core informational content remains unchanged. The output gains semantic structure, making the information more accessible and professionally presented.

Texinfo files are generally 10-30% larger than PSV files due to the additional markup and formatting tags. The increase in file size is a result of adding structural elements, cross-referencing capabilities, and documentation-specific metadata that enhance the document's usability and semantic richness.

Conversion limitations include potential challenges with complex nested data structures, loss of some raw formatting, and the need for manual review to ensure accurate markup. Not all PSV data may translate perfectly into Texinfo, especially if the original data contains complex relationships or non-standard formatting.

Avoid converting to Texinfo when dealing with extremely large datasets that don't require documentation formatting, when maintaining absolute data fidelity is crucial, or when the target audience prefers raw data presentation. Simple data transfer or analysis might be better served by keeping the original PSV format.

Alternative approaches include using Markdown for simpler documentation, keeping the original PSV format for data analysis, or using more specialized documentation tools like LaTeX for complex technical writing. The choice depends on the specific documentation requirements and target audience.
