What you need to know

E.164 formatter

Normalize phone inputs into a consistent international representation where enough country context exists. Formatting does not prove the number is valid or reachable.

CSV cleaner

Trim blank rows, normalize headers, and prepare a predictable file shape before upload. Keep the tool client-side when possible for simple data preparation.

Exact deduplicator

Measure repeated values and optionally produce a unique-value file while preserving a mapping strategy for the original rows.

Verification cost calculator

Estimate job composition using row count, expected duplicates, cache eligibility, and configured retail pricing. Label the result as an estimate until an actual preflight freezes a quote.

Tool-to-product handoff

Each tool should explain what it did, what it did not verify, and offer a clear next step into the relevant product/preflight flow.

FAQ

Questions about tools

Do these tools verify a number or email?

Not unless the tool explicitly creates a verification job. Formatting, cleaning, and deduplication are preparation steps.

Should I upload sensitive production data to a free tool?

Prefer client-side processing for simple utilities and follow your organization’s data-handling policy.

Is the cost calculator a final quote?

No. The final job quote is created by the real preflight using actual rows and current pricing rules.

Can I use the tools on mobile?

The interfaces should remain functional and expose the same substantive guidance on mobile.
