Formula Tester
Test Salesforce formulas without saving them
Write or paste a formula field or flow formula, supply the merge-field values by hand or prefill them from a real record, and see the result plus a breakdown of how it was derived — so you can find which branch of that nested IF went sideways.
What you can do
- Evaluate formula-field and flow-formula syntax without deploying anything
- Runs entirely in your browser — instant results, no AI tokens, no API calls
- A derivation breakdown showing how the result was reached, step by step
- Referenced merge fields are detected for you, so you know what to supply
- Prefill every referenced field from a real record with a single query
- Iterate as many times as you like at zero cost
How it works
Write or paste the formula
Anything you would put in a formula field or a flow formula resource.
Supply the values
Fill the referenced merge fields by hand, or prefill them from a real record with one query.
Read the derivation
See the result and how it got there — which branch was taken, and where it diverged from what you expected.
Why it's different
Zero risk, zero cost, instant
The usual way to test a formula is to save it into your org and watch what happens — which means a half-broken formula field briefly exists in production. This evaluates locally in your browser: nothing is written, nothing is deployed, no AI tokens are spent, and the answer is immediate. Prefilling from a real record is a single read.
Try asking
- Debug a nested IF that returns the wrong value in one edge case
- Check date arithmetic before committing it to a field
- Work out why a formula returns blank for one record and not another
- Draft a flow formula without saving a half-broken version
- Teach a new admin how a hairy existing formula works
