Salesforce test data generator — realistic records with relationships that actually connect

Syntharil generates schema-valid synthetic data for standard and custom objects: realistic names, emails, and addresses, valid picklist values, and parent-to-child relationships built automatically. Never “Test Account 1” again.

Empty sandboxes make everything slower: demos fall flat, QA misses bugs that only appear with real-shaped data, and every developer wastes time hand-crafting records. Generated data solves it only if it respects your schema — required fields, picklists, lookups, record types — and looks like something a real business produced.

How seeding works

  1. Connect and pick objects

    Authorize the org, choose the objects to seed, and set how many records of each you want.

  2. Tune the data

    Pick a generation method, override individual fields (skip, fixed value, pattern, range, or AI), and set the geographic mix.

  3. Generate

    Records are created parent-first with valid lookups, respecting field types, lengths, required flags, and picklist values — with live progress as they land.

What makes the data usable

Schema-valid by construction

Field types, lengths, required flags, and picklist values come from your org’s live schema — including custom objects and fields.

Relationships that connect

Parents are created first and children reference their real IDs, so Account → Contact → Opportunity chains work out of the box.

Realistic values

Names, emails, phone numbers, and locale-aware addresses that read like real records — not random strings.

Per-field overrides

Any field can be skipped, fixed, pattern-generated, range-bounded, or handed to the AI generator.

Geographic tuning

Control the US-versus-international mix so the data matches where your business actually operates.

Clean slate first

Optionally truncate previously seeded data before a run, so repeated seeding stays predictable.

Two methods: Standard and Persona-anchored

Standard generation uses Faker-style synthesis: fast, schema-valid, realistic-looking values for every field. Persona-anchored generation goes further — it builds coherent personas from industry preset libraries and keeps them consistent across objects, so a contact’s name, email domain, employer, and address all tell the same story. An optional deterministic seed makes runs reproducible.

For fields that need judgment — descriptions, notes, industry-specific text — AI-powered field generation writes values that fit the record’s context. The live AI Playground shows exactly what a field configuration will produce before you run anything.

Frequently asked questions

What is the best way to generate Salesforce test data?

For repeatable, realistic data with valid relationships, use a schema-aware generator: it reads your org’s field types, picklists, and lookups and builds records that pass validation, parents before children.

Does it work with custom objects and fields?

Yes. Generation is driven by your org’s live schema, so custom objects, custom fields, and their picklists and required flags are all respected.

How are relationships kept valid?

Objects are seeded in dependency order — parents first — and child records reference the real IDs that were just created.

Can AI generate field values?

Yes. Individual fields can be routed to AI generation for context-aware text, and the AI Playground previews the output before a run.

Can I wipe old test data before seeding?

Yes. A run can truncate previously seeded records first, so you always start from a known state.

What if I need real production data instead?

Use replication: it copies real records into a sandbox you own with PII masked in transit — synthetic and replicated data cover different testing needs.
