Pinned tabs
Pinned tabs stay visible in your workspace tab bar and persist in this browser.
Data & Storage
Drafts, recent items, favorites, outputs, and settings stay local to this browser.
Local project sessions
Sessions are stored in this browser only. If browser storage is cleared, local sessions may be lost.
Privacy & Analytics
Data Generator by OzCrypt runs locally in your browser. Your inputs, uploaded files, generated data, and outputs are not uploaded by this app. If usage analytics is enabled, basic app usage information such as page/tool views may be sent to Google Analytics to help improve the product. Do not include generated content in analytics events.
Analytics is optional and off by default. It never includes generator inputs, uploaded files, generated rows, data-plan contents, passwords, secrets, names, email addresses, addresses, or output values by design.
Essential local settings are stored in your browser so the app can remember preferences such as language and theme. Optional analytics is only used if you allow it.
App
Install may be available from your browser menu.
Security & Secrets
Configure password rules
Generate local passwords and test secrets. Use presets for fast defaults, then adjust the rules if you need a different shape or strength.
Batch count: 1 to 50.
Password mode
Balanced defaults for account passwords. Use advanced options to customize character sets.
Advanced options
Exported secrets are plaintext. Handle exported files carefully.

Salesforce
Configure Salesforce test data
Generate Salesforce-ready CSV test data with fields, rules, relationships, and export options. Review required fields, validation rules, record types, and lookup requirements before importing.
Add a seed to reproduce the same Salesforce-style output from shared setup links.
No Salesforce org connection is used. Picklist values, RecordTypeId values, required fields, and validation rules may differ by org.
| Field API Name | Type | Required | Unique | External ID | Picklist values | Lookup target | Generation rule | Actions |
|---|
Salesforce import helpers
Salesforce Metadata Helper (local paste/import)
Paste or upload simplified metadata-like CSV/JSON to prefill field rules. No Salesforce connection or API calls are used.
No metadata loaded yet.
Picklist values must match your org metadata. Bad picklist scenarios can intentionally output invalid values.
RecordTypeId values are org-specific. Map Label or DeveloperName to RecordTypeId manually.
OwnerId must exist in the target org.
External IDs support repeatable imports and safer sandbox-to-sandbox workflows.
System field warning
Some Salesforce system fields cannot be inserted or updated normally, including fields like CreatedDate, LastModifiedDate, SystemModstamp, and some audit fields unless special org permissions are enabled.
Relationship mapping is optional. Switch to Advanced mode to edit parent key distribution and lookup details.
Generate one child object and link each child row to an existing parent key.
Use Id for Salesforce Id mode, or an External ID field such as External_Id__c for External Id mode.
0 parent keys detected.
Data Generator by OzCrypt reads the first column locally. Nothing is uploaded.
Relationship mapping is disabled.
Relationship import warnings
Salesforce IDs are org-specific. Use existing IDs only when parent records already exist in the target org. External IDs are usually safer across sandboxes. Review lookup/master-detail requirements before import.
Salesforce Negative Import Scenarios
These scenarios intentionally generate invalid import rows for sandbox/test QA. Do not import negative packs into production.
All required fields valid with realistic synthetic values.
Advanced negative scenario settings
Picklist & RecordType Scenario Generator
Scenario coverage builder
Generate rows covering picklist values, blank optional picklists, RecordType test values, and optional negative rows for sandbox testing.
Adds intentionally invalid picklist and RecordType rows for QA.
Adds blank values only for non-required picklist fields.
RecordTypeId values are org-specific. Use DeveloperName or mapping carefully and confirm values in your target org.
No picklist/RecordType scenario matrix generated yet.
No rows generated yet.
Salesforce import warnings
No Salesforce org connection is used. Picklist values must match your org. Required fields, validation rules, and RecordTypeId values are org-specific. Review before import.
SOQL sample query generator
Local SOQL examples from current schema
Generates sample SOQL strings using your configured object/fields. No Salesforce org validation or API connection is used.
No SOQL samples generated yet.
Relationship names may differ by org. Verify object/field names and relationship API names before use.
No data plan loaded.
Generated locally. No signup. No server upload in this standalone build. No Salesforce API calls. Synthetic values only.
Test-only dataset reminder
Values are synthetic/test-only. This module creates files for review and import. It does not import directly into Salesforce.
Salesforce workflow
Parent-Child Pack Generator
Generate parent and child Salesforce-style rows locally with consistent lookup/external ID references and clear import order guidance.
Use a seed to reproduce the same parent-child dataset from shared setup links and presets.
Example: Account_External_Id__c for external-id strategy, or AccountId for Salesforce Id-style mapping.
Used by exact count and percentage modes.
Relationship preview: Contact.Account_External_Id__c -> Account.External_Id__c
All parent/child references are valid for import.
Import warnings
External ID field names may need to be adjusted for your org. Review validation rules and required fields before import.
