Snake_case writes compound words in lowercase separated by underscores, like 'my_variable_name'. It is common in Python, Ruby and database column names.

How does it convert to camelCase?

Each underscore is removed and the first letter of every word after the first is capitalised, so 'my_variable_name' becomes 'myVariableName'.

Is my text uploaded anywhere?

No — the conversion happens entirely in your browser and nothing is sent over the network.
