PDF, DOCX, CSV, and JSON
Choose file formats for common tasks. Read a concrete example, examine the trade-offs, and try a small exercise to see whether the principle applies to your situation.
Understand the digital risk
- Start here. PDF preserves presentation but can be harder to edit.
- Add context. CSV stores plain tabular data without complex formatting.
- Keep in mind. JSON carries structured data; validate its encoding before sharing.
How it appears in practice
A PDF preserves a fixed document layout for sharing, while DOCX is generally more convenient for ongoing editing. CSV is a simple table exchange format; JSON can represent nested data structures that CSV handles poorly.
Use the simplest format that preserves what the recipient actually needs, and retain an editable master when possible.
Where to be careful
A file extension does not guarantee that a file is safe or correctly formatted. CSV may mishandle leading zeros or spreadsheet formulas when opened without care.
Check your own settings
Choose a file format based on the next person’s task: read, edit, calculate or exchange structured data. Test opening the file in the intended application.
