Frequently Asked Questions
What delimiter should I use?▾
Comma is the standard for CSV files. Use semicolon if your data contains commas (common in European locales). Tab-separated is great for data copied from spreadsheets. Pipe is used in some legacy systems.
Can it handle quoted fields?▾
Yes. The parser correctly handles fields wrapped in double quotes, including fields that contain commas, newlines, or escaped quotes within the quoted value.
Is there a file size limit?▾
There's no hard limit since processing happens in your browser, but very large files (>50MB) may cause your browser to slow down. For typical CSV files (thousands of rows), it works instantly.
