Parse URL Column in NDJSON Files Online

What parts of a URL does the NDJSON URL parser extract?

Protocol (scheme), host (domain), port, path, query string, individual query parameters as separate columns, and fragment. Each component is extracted into its own column in the output file.

Why would I need to parse URLs in a NDJSON file?

Common uses include extracting UTM parameters from marketing URLs, isolating hostnames for domain analysis, splitting path segments for web analytics, and cleaning URL columns before loading into a database. Web server logs, analytics exports, and CRM data often contain raw URL columns that need decomposing.

What happens to malformed URLs in a NDJSON file during parsing?

Rows with values that cannot be parsed as a valid URL will have NULL in all extracted component columns. The original URL column is preserved so you can identify and fix malformed entries separately.

Is my data private?

Yes — completely. Your file is never uploaded to any server. Everything runs locally in your browser using WebAssembly — processing happens entirely inside your tab. Once you close the tab, nothing is retained.

What is the maximum file size?

The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines handle 500 MB to 1 GB comfortably.
