TSV (Tab-Separated Values) uses tabs as field delimiters, one record per line. CSV (Comma-Separated Values) uses commas. TSV's advantage: tabs appear far less frequently in data than commas, requiring less escaping. TSV is the standard export format for many databases and data warehouses like BigQuery and PostgreSQL.
① Data analysis: Convert spreadsheet or database exports to JSON for web apps ② Data import: Load TSV data into NoSQL databases like MongoDB ③ API development: Convert tabular data to JSON for API responses ④ Batch processing: Bulk convert structured text to JSON ⑤ Data migration: Use as an intermediate format between systems
TSV files typically have column names in the first row (e.g., Name, Age, City). Using the first row as keys maps each subsequent row to {Name:'...', Age:..., City:'...'}. This creates clean, meaningful JSON structure. Without this option, data becomes array entries with col0, col1... keys.
Standard TSV uses double quotes to wrap fields containing special characters (tabs, newlines, double quotes). Double quotes themselves are escaped as two double quotes. This tool supports basic quoted field parsing.
No. Everything runs locally in your browser. Your tabular data never reaches any server. All processing happens on your device, ensuring data privacy.
