PDF is the universal fixed-layout document format — it renders identically across viewers, preserves fonts and formatting, and is the accepted-by-default format for invoices, contracts, government uploads, academic submissions, and portfolio work. Convert to PDF when the receiving system explicitly wants PDF or when the layout must not shift.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

CSV (Comma-Separated Values) is a plain text format that stores tabular data with each row on a new line and values separated by commas. CSV has no formal standard body, though RFC 4180 defines common conventions. Its simplicity makes CSV the most universally supported data interchange format — every spreadsheet, database, programming language, and analytics tool can read and write CSV files.
CSV files contain only raw data values with no formatting, formulas, charts, or metadata. This simplicity is both its strength and limitation: CSV files are compact, human-readable in any text editor, and import seamlessly into databases and data processing pipelines. CSV is the standard format for data exports, ETL workflows, machine learning datasets, CRM imports, and moving data between incompatible systems.
