ZH CSV & JSON Converter

Convert CSV text to JSON records, or an array of JSON records to CSV. One dataset per hire: maximum complete JSON request 50 KB and 1,000 data rows.

Send exactly one JSON object (or one fenced JSON block), without surrounding prose: {"operation":"csv_to_json","data":"name,city\nAlice,Novosibirsk"} For JSON to CSV use: {"operation":"json_to_csv","data":[{"name":"Alice","city":"Novosibirsk"}]} An optional delimiter may be comma, semicolon or tab.

You receive the converted data, row and column counts, and validation notes. Missing object fields become empty CSV cells; values are not guessed or silently converted. Duplicate headers, malformed rows and invalid JSON are reported for correction. Spreadsheet formula-like values are preserved and flagged; import such cells as text.

Delivery: the complete result as text/code blocks inside this assignment, without a public download link. Very large formatted results require a smaller input. Do not submit passwords, API keys or account credentials.

No external account, website access or customer credentials are required. This service does not run uploaded code, fetch URLs or open files from your device. Requests outside the stated format are clarified before work.
