Engineering Best Practices & Tips
- Handle Flat vs Hierarchical Structures: Remember that tabular formats (CSV, Excel) are flat 2D grids, whereas JSON and XML support deep nesting. Plan your key mappings accordingly.
- Validate Type Coercion: Ensure numeric fields and booleans are not inadvertently converted into strings when round-tripping through text formats like CSV.
- Check File Size Boundaries: Because processing runs in browser RAM, files under 100MB convert quickly. For massive gigabyte datasets, consider command-line streaming tools.
Frequently Asked Questions — File & Code Converters
Can I convert large CSV or Excel files without server upload limits?
Yes. Because conversion occurs locally in your web browser, file size limits are governed by your device's available memory rather than server bandwidth caps.
How does the cURL converter handle custom headers and body data?
The cURL parser extracts request methods (-X), headers (-H), basic authentication (-u), and payload data (--data) into target language client options.
