📊 CSV to JSON Converter
Convert CSV (comma‑separated values) into clean JSON. Choose delimiter, header handling, and trim fields. 100% client‑side.
📖 How to Convert CSV to JSON (Step by Step)
- Step 1: Paste your CSV data into the left text area (or use the "Load Sample" button).
- Step 2: Choose the delimiter that matches your CSV (comma, semicolon, tab, pipe).
- Step 3: Decide whether to use the first row as JSON object keys (headers) or generate generic keys (col0, col1…).
- Step 4: Optionally enable/disable field trimming (removes surrounding whitespace).
- Step 5: Click "Convert to JSON" – the JSON output appears on the right. Copy or download the result.
💡 Why Convert CSV to JSON?
- ✔️ JSON is the standard data format for web APIs and JavaScript applications.
- ✔️ Easily import spreadsheet data into databases or front‑end apps.
- ✔️ All processing is local – your data never leaves your device.
💡 Pro Tip: Enable "Trim fields" to remove accidental spaces around CSV values. The converter also auto‑detects numbers and converts them to proper JSON numbers.
