How to clean AI tables
Short answer
Clean AI tables by deciding which row is the header, normalizing every row to the same number of columns, removing spacing noise, and exporting to the format your next tool expects.
Common AI table problems
AI tables often copy with broken pipes, uneven spacing, missing cells, or Markdown separators that do not belong in CSV or JSON. Cleaning the table locally makes the next paste safer.
- Identify the headerThe first row should name the fields. Rename empty headers before exporting to JSON.
- Normalize columnsEvery row should have the same number of cells so spreadsheets and parsers do not shift values.
- Choose the outputUse Markdown for docs, CSV for spreadsheets, TSV for safer copy-paste, and JSON for scripts.
- Review empty cellsAn empty cell can be intentional, but in AI output it often means the model skipped a value.
