How to use Text Splitter

Break long documents into fixed-size chunks of up to 2,000 characters. Each chunk ends at a whitespace boundary so no word is cut in half, which means a chunk can end mid-sentence. Useful for fitting content through prompt and paste limits.

  1. Copy the text or table you want to fix.
  2. Paste it into the input above. The result updates instantly.
  3. Copy, download, share, or embed the finished result.
