We have a requirement where we need to clear each fields which are just lying in the system and not used any where to make environments more cleaner, Is there any way to do this. I used eclipse earlier for reverse process where we chose any field and can find its reference.
This might not be exactly what you're looking for, but Salesforce does offer an "Optimizer" feature, which examines your org, and reports possible improvements in a few areas. One of those areas is field usage, allowing you to see fields which have not been populated in about 6 months.
A few categories reported by a Optimizer report generated a few months ago:
- Field Limits per Object
- Field Usage per Object
- Field Usage per Page Layout
