Dennis @ PerfectForms
To get the data from a large Multiline text input out of PerfectForms you will need to use the Connection Agent to write to an outside database. Our help guide describes the Connection Agent:¬ http://www.perfectforms.com/Documentation/manual/html/?lookup_agent.htm. It is a much better method than exporting anyway. You can set it up to write to your DB as part of the workflow of your form so your DB will always be live, and the data/fields you export will be in your schema, not PerfectForms’ schema.
If you need assistance installing or configuring the Connection Agent, please submit a support inquiry and we will be happy to assist you:¬ https://www.perfectforms.com/help-center/support-inquiry/.
