Convert Headerless TSV/CSV Data

Converting Data Without Headers

Not all tabular data files include a header row. Sensor readings, log entries, and raw data dumps often consist entirely of data rows with no column names. The TSV/CSV converter handles this by allowing you to toggle the header row setting.

Example: Sensor Readings (TSV)

1709136000	23.5	45.2
1709136060	23.6	45.0
1709136120	23.4	45.3
1709136180	23.7	44.8

Converted to CSV

1709136000,23.5,45.2
1709136060,23.6,45.0
1709136120,23.4,45.3
1709136180,23.7,44.8

Header Toggle Behavior

When the Header Row toggle is turned off:

• The data preview table displays all rows as data (no bold header row)
• The row count reflects all rows, not all-minus-one
• No special treatment is given to the first row during conversion

When the toggle is on (default):

• The first row appears as bold column headers in the preview
• The row count shows data rows separately from the header
• Conversion behavior is the same in both cases — this setting only affects the preview display

Detecting Headers Automatically

There is no universal way to detect whether a file has headers. Some heuristics include checking if the first row contains non-numeric values while subsequent rows are numeric, but these are unreliable. The converter lets you make this decision explicitly.

Use with Positional Data

Many scientific and engineering data formats use fixed column positions without headers. Converting these between TSV and CSV preserves the column order and values exactly.
