Questions
Which CSV files work?
Standard CSV (RFC 4180) and the common variations: fields in double quotes can contain commas, line breaks and doubled quotes (""). The separator (comma, semicolon, tab or pipe) is detected automatically; spreadsheets in many European languages use semicolons.
What does “Convert numbers and true/false” do?
It turns 36 into the number 36 and true into a boolean, instead of keeping them as text. Values that would change as numbers, like 007 or very long IDs, stay as text.
How is JSON turned into CSV?
A list of objects becomes a table: each object is a row and each key a column, in the order first seen. Nested objects and lists are written as JSON text inside the cell. A list of lists is written row by row.
Does the CSV open correctly in Excel?
Yes, fields are quoted where needed and lines end the Windows way (CRLF). If your Excel uses semicolons as its list separator, choose “Semicolon” before converting.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
