| Formatting | Plain text only, no styling | Column alignment, bold headers, inline formatting |
| Version control | Difficult to diff, shows as one line change | Git-friendly, shows row-by-row changes |
| Embedding | Requires import or conversion | Native display in README files and docs |
| File size | Compact, minimal punctuation | Larger due to table formatting syntax |
| Use case | Data storage, import/export, analytics | Documentation, wikis, GitHub repos |
