From your industry to a validated dataset

Pick an industry, start from a template or your own sample, shape the fields - Data Genly generates the rows and checks them before you download.

Start from your industry

10 industries: Healthcare, banking, insurance, retail, FMCG, real estate, construction, logistics, telecom and hospitality - products, job titles and companies follow the one you pick.
35 templates: Five general ones (customers, employees, products, invoices, orders) plus three for each industry.
Your column list: Upload a CSV with your headers and get a field for each column, with types detected from the values.
Your sample data: Upload example rows as CSV, Excel or JSON. ID prefixes, codes, categories and ranges follow your sample - the values never do.

23 field types: Text, numbers, currency, dates, email, phone, URL, country, city, address, postcode, UUID, barcodes, ratings, lists, running numbers, code patterns and more.
Rules: Ranges, percentage splits, unique values, required fields, a share of empty values and running IDs with your own prefix.
Related tables: Customers → orders → order items, linked by keys, with how many children each parent gets. Paid plans.
Rules between columns: Dates in order, totals above subtotals, if-then conditions. Paid plans.
Test data mode: Deliberately broken cells - bad emails, missing values, duplicates - for testing validation. Paid plans.
Localization: Country, language and currency conventions for names, phones, addresses and money - or a mix of countries in one dataset.
Live sample: Ten rows from the real generator, updated as you edit.
Saved schemas: Keep a setup and generate from it again with one click.

Up to millions of rows: Rows stream to the file as they are made, so large datasets don't slow down.
Background generation: Live progress; leave and come back, or cancel. Failed and cancelled runs are never counted.
Validation summary: Unique values, valid formats and required fields checked on every dataset.
CSV, Excel, JSON and SQL: Meaningful file names and private links that expire. SQL on paid plans.

Synthetic only: Every value is generated. Nothing is copied from real people.
Samples read, not kept: Uploaded files are read in memory for their formats and discarded straight away.
Files expire: Generated files are deleted automatically after your plan's retention period.
Spreadsheet-safe: Values that could run as spreadsheet formulas are neutralised in CSV and Excel files.
