FAQ
Why TSV instead of CSV from spreadsheets?
Excel and Google Sheets copy selected cells as tab-separated values — pasting directly here preserves columns without a CSV export step.
What if my values contain tabs?
Quoted fields may contain tabs; unquoted embedded tabs will split the cell — avoid raw tabs inside values.
Can I get an array of arrays instead of objects?
Uncheck "First row is header" to get arrays with col1, col2… keys per row.
