Header row is being used to name object keys.
Output is formatted for readability.
Blank rows are removed before conversion.
Output is returned directly without a wrapper key.
Turn a spreadsheet export into records
Use the first row as headers when each line should become an object. Turn that off if the CSV has no header row and you need arrays. Check the detected columns before copying the result.
Two-line CSV example
name,score followed by Ada,7 becomes [{"name":"Ada","score":"7"}] in object mode. The value "7" is still a string; convert numeric fields after import if the destination requires numbers.
Check headers and empty rows
Blank or duplicate column names can produce confusing keys. Review the preview and choose whether empty rows belong in the exported data.
