]Frequently asked questions
What is TSV?
TSV stands for tab-separated values. It is like CSV, but columns are split by a tab character instead of a comma, which is handy when your values already contain commas.
How is TSV different from CSV?
Both store rows of columns. TSV uses tabs between fields, so commas inside a value need no quoting. CSV uses commas and relies on quotes to protect values that contain them.
Does the first row become the keys?
If you enable the header option, yes. Each column header becomes a key and every following row becomes a JSON object.
Are numbers kept as numbers?
With typing on, values like 42 and true become a number and a boolean instead of strings. Turn it off to keep everything as text.
Is my data uploaded anywhere?
No. The conversion runs entirely in your browser, so your TSV never leaves your device.
