exporting field help text and description in bulk
TIL that you can create custom report type on entity definition + field definition to report on your fields!
h/t : https://www.asagarwal.com/how-to-report-on-objects-and-fields-defined-in-salesforce/ and Anna Loughnan
However I could not include field help text, though it is listed in the tooling api docs for fielddefinition
then i tried a custom report type on entity definition with entity particle, and added field definition via lookup
this worked in theory - i could include description and inline help text.
but when i ran the report, field description remained blank. other folks said the report type worked for them, so i should test more as the report types would be really simple to use. so try that first.
instead I ran a soql query to test it out, and this works
select entitydefinition.label, inlinehelptext,fielddefinition.description,fielddefinition.label from entityparticle where entitydefinition.label = 'Opportunity'
and you can also include the defaultValue for the field by adding the DefaultValueFormula field
select entitydefinition.label,inlinehelptext,fielddefinition.description,fielddefinition.label,DefaultValueFormula from entityparticle where entitydefinition.label = 'Opportunity'
there are a bunch more options, have not explored them all. see the docs and figure out what is useful for your use case!
