CSV import readiness · Free-first

Stop bad supplier CSV files before importing.

Headers change. Records go missing. A spreadsheet export arrives with surprise columns. Get a concrete local audit at zero cost—or commission a reproducible, small CSV-to-import-template cleanup for your own authorized data.

This is a separate, optional human-scoped project, NOT the existing 0.005-USDC x402 automated CSV API. No confidential data upload, wallet connection or payment is required to evaluate the free script. Actual paid project orders received: 0.

Proof before payment

Run a real, no-upload CSV structure audit

The free Python 3 script uses only the standard library and parses up to 2 MiB. It reports totals for uneven rows, missing cells, repeated header labels, exact duplicate records and possible formula prefixes without printing your rows or filenames. Quoted commas, escaped quotations, embedded line breaks and UTF-8 BOMs are supported.

1. Inspect the source

Download Python script

Source, MIT license and 19 reproducible test cases ↗

The standalone free script itself has no network calls, login, wallet, external packages or file mutations. Audit source before you run any code.

2. Run locally (no server)

python3 csv-import-audit.py --demo
python3 csv-import-audit.py --file sample.csv

Only run on a CSV you are allowed to inspect. The script is deliberately bounded and does not repair or sanitize your data.

Actual fictional demo output

Data rows: 5
Header columns: 3
Uneven-length data rows: 1
Missing cells: 3
Duplicate data rows: 1
Duplicate header names: 0
Possible spreadsheet-formula prefixes: 1
Upload requests: 0 · Wallet signatures: 0 · Paid amount: 0 USDC

Demonstration includes only fictional values (Ada, Lee and an example.invalid URL). Exact output is generated by the public script; no fabricated customer dataset or third-party purchase is claimed.

Paid work only if it saves you time

Optional 25 native Base USDC CSV import pilot

Defined one-file scope

One owner-authorized, non-confidential CSV source, up to 2 MiB / 10,000 data records / 25 columns.
Up to three agreed cleanup or target-column mapping rules with examples. We do not invent missing information or make unsupported financial claims.
Deliver the cleaned/restructured CSV where feasible, an exception list/count summary, and a reusable Python 3 script with reproducible tests.
One correction within the original approved three-rule scope. Estimated three working days after all contract and lawful file conditions are met; the binding deadline is agreed first.

How to request work safely

Send only the intended column headers, row count, synthetic or redacted examples, three desired transformations and deadline. Do not email actual regulated or confidential records initially.
Receive an honest suitability decision, exact scope, privacy controls and final price. Some large or nonstandard files will be declined or quoted separately.
Agree delivery, permitted data handling, recipient and possible refund/cancellation terms in writing before a Base USDC payment. No surprise auto charges, deposit bonds or bank credentials.
After consent and a lawful payment arrangement, receive source/results and a summary with remaining exceptions.

What this is not: a subscription, automatic x402 purchase, escrow agreement, marketplace verified seller badge, confidential-data processor, cryptocurrency investment, KYC bypass, data certification or guarantee of flawless imports. The 25-USDC amount is an offer for a proposed bounded scope, not a received invoice or existing contract.

Want only a tiny automated API call?

For up to 32 KiB, the independent free browser CSV checker + optional 0.005 USDC x402 API remains available. That is a different product for automated structural QA of small samples. A paid API's HTTP 402 quote is not a completed sale; all payments require buyer approval.
