Convert TSV to YAML

We turn TSV into YAML right in your browser — the file never goes to a server.

What you will lose

Nothing important: the target format does everything the source does.

TSV

Good at

  • Separated by tabs, and tabs are rare inside real text
  • Fewer reasons to quote a field than in CSV
  • Read by Excel, R and almost any database export

Awkward about

  • Tabs are invisible: a broken file looks exactly like a good one
  • No nesting, same as CSV
  • Editors like to replace tabs with spaces and break the file

Use it when

  • The data contains commas and CSV falls apart because of them
  • An export from a database or a research tool
  • The file is going into R, pandas or Excel

YAML

Good at

  • Reads like prose: indentation instead of braces
  • Comments — the only one of the three that has them
  • Nesting and types, same as JSON

Awkward about

  • Indentation carries meaning: one space changes it
  • Unquoted yes and no behave in surprising ways
  • Parsing is heavier and slower than JSON

Use it when

  • A configuration file edited by hand
  • You need notes sitting next to the values
  • The data is nested and a human will read it

Common questions

Does the file get uploaded to a server?
No. TSV → YAML runs right in your browser and the file never leaves your device. It only goes to a server if the browser cannot cope — and then we delete it within a couple of hours.
Is nesting preserved?
Yes, YAML stores objects inside objects, so the structure arrives as it is.
Can I get the original quality back afterwards?
Yes, YAML supports lossless compression, so you can go back to the original.
How many files, and how large?
Up to 20 files at a time, 20 MB each. No sign-up, no watermarks.
