TSV vs CSV — when to convert

TSV is the natural output of many Unix tools like psql and awk. Converting it to CSV produces the format that spreadsheet applications and most import tools expect.

Aspect	TSV (tab)	CSV (comma)
Delimiter	Tab character	Comma with quote escaping
Data containing tabs	Problematic	Safe after conversion
Data containing commas	Already safe	Quoted automatically by this tool
Tooling	Unix/psql/awk native	Excel and most SaaS imports native
Best for	Scripted data extraction	Sharing and spreadsheets

Bringing tab-separated exports back into standard CSV

Databases and Unix tools frequently export TSV. Re-separating with commas produces a standard CSV that Excel, email clients and BI tools open without a second thought.

Input TSV

id	name	role
1	Ada	admin
2	Grace	dev

Converted CSV

id,name,role
1,Ada,admin
2,Grace,dev

Paste a tab-separated file from a psql or awk export and download a standard CSV everyone can import.
