What Show TSV Structure can do:

Show TSV Structure gives you a quick look at the layout of your tab-separated values. It identifies column headers, counts how many columns there are, and optionally shows a sample value from the first data row. You can also enable basic type guessing to check whether values look like numbers, booleans, or plain text. This tool helps you understand unfamiliar TSV files without writing scripts or opening them in a spreadsheet. It’s ideal for developers, analysts, or anyone dealing with structured data on the fly.

Example:

Input:

id	name	age	joined
1	Alice	30	2020-01-01
2	Bob	25	2021-06-15

Output (with all options ON):

Column	Name	Type	Sample Value
1	id	int	1
2	name	string	Alice
3	age	int	30
4	joined	string	2020-01-01

Common Use Cases:

Use this when reviewing logs, inspecting exported TSVs from databases, or validating that your data’s structure matches expectations. It’s a fast way to sanity-check columns and values before importing, cleaning, or reformatting your file.

Useful Tools & Suggestions:

After using Show TSV Structure to get a feel for the layout, try Count TSV Columns to confirm how many fields you’re working with. And if you’re planning to reshape the data, Rotate TSV Columns gives you a whole new perspective.
