You can access the form data as json using form.data

For eg

Consider the form defined as below,

class GeneralForm(FlaskForm):
    boolean_val = BooleanField('Boolean')
    a_float = FloatField('Severity')
    submit = SubmitField('Submit')

In the app route,

@app.route('/wtforms', methods=['GET', 'POST'])
def debug_wtforms():
    form = GeneralForm()
    if request.method == 'POST' and form.validate_on_submit():
        print(form.data) # Form data as a dict
    return render_template('index1.html', form=form)

If you have simply defined the form directly in the html template, you can access the form data using, request.form.to_dict(flat=False)

I hope this helps.
