Frequently Asked Questions
What is the difference between CSV and TSV formats?
CSV (Comma-Separated Values) uses commas (`,`) as delimiters, requiring text cells containing commas to be escaped in quotation marks. TSV (Tab-Separated Values) uses raw tab characters (`\t`) as field delimiters. TSV is widely used in bioinformatics, scientific computing, and spreadsheet clipboard copying because text fields rarely contain raw tab characters.
How do you copy data directly from Excel or Google Sheets into TSV to JSON?
When you select and copy cells in Microsoft Excel or Google Sheets (`Ctrl+C`), the operating system clipboard automatically formats the tabular data as TSV (tab-separated columns and newline-separated rows). Simply paste (`Ctrl+V`) into our editor to convert spreadsheet cells directly into clean JSON.
How are empty TSV cells handled during JSON conversion?
Consecutive tab characters (`\t\t`) represent empty fields. You can configure the converter to parse empty fields as `null`, empty strings `""`, or omit the key entirely from the resulting JSON object.
Is TSV better than CSV for tabular data with complex text descriptions?
Yes. TSV is often preferred for datasets containing prose, addresses, or SQL query text because sentences frequently contain commas and quotation marks. In TSV, commas and quotes do not require escaping, reducing syntax parsing errors.
