A random string generator creates synthetic identifier, token and code-like values for test data, validation flows and import fixtures. It can return UUID, ULID, Nano ID style, alphabetic, alphanumeric, binary, hexadecimal, numeric, octal, symbol and custom-character output from one endpoint.
Generate sample string data at spotzee.com/tools/random-string-generator.

​
Why this matters

String fixtures look simple until a validator, parser or import job sees a value it did not expect. One hand-written ID will not test length limits, casing rules, prefixes, base-number strings, symbol handling or custom character sets. Synthetic string data gives you controlled variation. And a numeric seed lets you reproduce the same records after a failure without pinning hand-written IDs in fixture files forever. Generated strings are test data only. They are not credentials, secrets or production identifiers. Each Extended API call deducts a small per-call amount from your Spotzee credit balance. See the Spotzee pricing page for live per-tool pricing.

How it works

1

Send the request

POST to /generic/data/generate/string with count. The count is a string from 1 to 100.
2

Choose a method

Use method=profile for expanded string records, or choose one field method: alpha, alphanumeric, binary, fromCharacters, hexadecimal, nanoid, numeric, octal, sample, symbol, ulid or uuid.
3

Set string controls

Send length, casing, prefix, character-source, exclusion, leading-zero and reference-date parameters only when the selected method supports them.
4

Set repeatability

Send locale where supported and an optional numeric seed when the same output needs to repeat in tests.
5

Read the response

The response returns data.strings[], generated, locale, optional seed, and the resolved method.

sampleSampled ASCII stringcount, locale, seed, length controls
symbolSymbol stringcount, locale, seed, length controls
ulidSortable identifiercount, locale, seed, refDate
uuidUUID valuecount, locale, seed
Use profile when you need many string fields together. Use a field method when your form, parser or import job only expects one string shape.

What to watch for

  • Count outside 1 to 100. One request generates up to 100 string records. For more rows, call the endpoint again and vary the seed when you need a different batch.
  • Exact length mixed with range. Use either exact length or a minimum/maximum length range. Do not send both.
  • Length on UUID or ULID output. Length controls work with random, base, custom, Nano ID and profile output, not uuid or ulid.
  • Missing custom characters. method=fromCharacters requires a characters value.
  • Prefix on the wrong method. Send prefix only with binary, hexadecimal, octal or profile.
  • Reference date on the wrong method. Send refDate only with ulid or profile, and use an ISO 8601 date-time with a time-zone offset.

FAQs

It creates synthetic string values for tests, fixtures and validation workflows. Spotzee can return UUID, ULID, Nano ID style, alphabetic, alphanumeric, binary, hexadecimal, numeric, octal, symbol and custom-character output.
Yes. Choose method=uuid to generate UUID values, or choose method=ulid and method=nanoid when sortable or compact identifiers fit the test better. The same endpoint works as a ULID generator and also supports expanded profile records.
Yes. Use method=symbol for symbol-only values, or use method=fromCharacters with your own character source. This makes the endpoint useful as a random string generator with special characters for validation and parser tests.
Yes. Set a numeric seed to reproduce output for the same count, locale, method and option values. Leave the seed blank when you want a fresh random batch for exploratory QA.
Yes. The generated values are plain strings, so they can be pasted into Java, Python, JavaScript or any test fixture format. Use seeded output when a failing test needs repeatable IDs or tokens.
Read the random string generator guide for endpoint options, response fields and integration patterns. The guide also shows where string fixture data fits beside developer fixture, word, lorem ipsum and git generators.
