Unspaced Korean terms such as flu vaccination and flu symptoms are separated. Expressions involving particles and verbs are also analyzed, including food good for a cold and ways to prevent flu. Register preferred spacing for proper names or edit the result directly.

Frequently Asked Questions

Which tables can I paste?

Paste tab-separated tables copied from Excel or websites, CSV, Markdown tables or one-keyword-per-line lists. A keyword or search-term header is detected automatically. You can select a different column if needed.

What is kept in Korean-only output?

Latin letters, symbols, URLs and emails are removed from the selected keyword column. Meaningful numbers, such as a count or product model number, are kept by default. Turn off Keep numbers to remove them. Other columns such as search volume and competition are excluded.

Is spacing always accurate?

A search-word dictionary and Korean morphological analyzer distinguish words from particles. Particles stay attached to the preceding word, and the next word is separated. Counts such as 5 items are preserved. Proper names and ambiguous expressions may need a review; custom spacing and direct result editing are supported.

How are duplicates handled?

With duplicate removal enabled, keywords differing only in spacing count as duplicates, and the first one is kept. Original order is preserved. You can also turn duplicate removal off.

Is my pasted table sent to a server?

No. Extraction and spacing cleanup run only in your browser. The input, result and custom dictionary are not sent to or stored on a server. Limits are 250,000 characters, 5,000 rows and 64 columns per run.
