CSV Tools: Tips & Best Practices
Handling CSV reliably requires consistent delimiters and careful handling of quoted fields.
Choose a Delimiter
Select the correct delimiter early (comma, tab, semicolon) to avoid parsing errors.
Quoted Fields
Always handle quoted fields correctly and watch for embedded newlines.
Validate Headers
Confirm header rows match expected schema before conversion.
Normalize Types
Coerce numeric and date types explicitly to avoid downstream surprises.
Keep Samples
Keep small sample files for testing conversions and schemas.
Chunk Large Files
Process very large CSVs in chunks to avoid memory spikes in the browser.
