About this tool

Extract the last N rows from a TSV file. Useful for inspecting recent records in time-ordered data or checking what was appended to a log.

Frequently Asked Questions

What is the difference between tail and head for TSV files?

Tail returns the last N rows. Head returns the first N. Use tail to inspect the most recent records in time-ordered data.

Is tail slow on large TSV files?

The tool needs to reach the end of the file, so tail takes longer than head on very large files. For columnar formats like Parquet, it is still fast because the engine can seek efficiently.

Can I combine tail with sorting for TSV files?

Not in this tool. For more control use the SQL Query tool with ORDER BY col DESC LIMIT N to get the top N rows by any sort order.

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.
