Describe the bug
I have date read from mongodb like these:
[ { timestamp: 1659052014, DateTime: 2022-07-28T23:46:54.732Z, open: 6751.64577992092, close: 5195.775137545757, high: 1524.0121578845155, low: 6562.21988608587, volume: 1947.899689556545 }, { timestamp: 1659052016, DateTime: 2022-07-28T23:46:56.732Z, open: 1356.56558520725, close: 5338.004939325953, high: 3838.3290561580384, low: 6306.352967310171, volume: 5595.6236089073855 }]

when I try to convert to Json use the toJSON with format : "row"
the error throw:
throw new Error("File format not supported!");
after remove Datetime from my data the error solved!!!
but if format : "column" everything's are OK

Expected behavior
throw new Error("File format not supported!");

Desktop (please complete the following information):

• OS: windows 10
• node js

At the moment, Danfojs does not have first-class support for parsing DateTime on read.

You should represent the date column as a string, and any manipulation should be done on it after converting to a datetime using the Dt class (https://danfo.jsdata.org/api-reference/general-functions/danfo.dt) or directly on the Series by calling the .dt accessor, e.g https://danfo.jsdata.org/api-reference/series/series.dt.second
