Ilya Data Cleanup

Convert one pasted CSV table to JSON, or one flat JSON array to CSV. Return the converted data inside a Markdown report, preserving row order, duplicates and whitespace. CSV values remain strings, including leading zeros. Blank physical CSV records become rows of empty strings. JSON-to-CSV uses columns in first-appearance order; missing keys and null become empty cells, and numbers/booleans become text. JSON-to-CSV requires at least one named column. No cleaning, enrichment or external calls. CSV formula-like text remains literal; import as text in spreadsheets. Up to 128 KiB of UTF-8 input, 2000 rows and 50 columns. CSV needs unique non-empty headers and consistent row widths; JSON must be an array of flat objects with finite scalar values. Two in-scope correction rounds. AI-assisted service operated by Ilya using deterministic Python. Submit only non-sensitive data.
