Each tool has one purpose. Try the sample first, inspect what it produces, then choose an offline edition if it fits your workflow.

For a small CSV handoff

CSV Preflight Desk

Make each cleanup decision visible before the file reaches a spreadsheet or an import process.

Select required columns; missing facts remain missing.
Choose whitespace trimming and exact whole-row duplicate removal.
Export the cleaned CSV, trimming log and issue list separately.

For comma-separated UTF-8 CSVs with up to 30 columns. No fuzzy matching, field mapping or automatic import.

Inspect a real export from fictional input

Four supplied rows were run through the browser trial. The repeated row was removed, the blank email was left unresolved, and the formula-like note gained an apostrophe in the export.

To reproduce: trim on, remove exact duplicates on, email required. Spreadsheet safety prefixes may be retained literally by another importer; inspect the destination rules.

FOR A DEVELOPER HANDOFF

QA Evidence Desk

Keep reproduction steps, expected and observed results, evidence references, owner and next action together. Unknown or untested work stays visible.

Offline outputs: reloadable project JSON, issue CSV and Markdown handoff. Up to 500 manually entered issues.

The free sample lets you enter records and inspect the handoff preview. File import/export is included in the offline edition. This is a manual workspace; it does not find bugs or verify evidence.

One download.
Your own working copy.

The download includes a standalone HTML tool for a desktop browser. No subscription or cloud account is needed to use the tool; a BOOTH account is needed for the purchase.

Check the sample

Try fictional or non-sensitive data. Confirm the workflow and outputs before choosing a product.

Purchase on BOOTH

The buttons open the actual product listing. Follow BOOTH's account, checkout and payment instructions. Prices are in JPY; payment availability depends on your country and provider.

Unzip and open

After confirmed payment, download from your BOOTH purchase history or library. Unzip the folder and open index.html in a desktop browser. Save or export before closing. BOOTH's download instructions.

Before you choose.

What is included, and may I use it for clients?

Each ZIP includes the standalone English HTML tool, English usage guide, license and fictional examples. You may use it internally in your business and share completed client outputs. Reselling or redistributing the blank tool or template is excluded. Individual consulting, implementation and support contracts are separate.

Where does my data go?

The downloaded tools use no network libraries, cloud uploads, telemetry or autosave. They process input in the page and export files you choose to save. Your browser extensions and any later sharing are under your control. Use fictional or non-sensitive data for the online samples.

Will the tool certify my file or tell me what will earn money?

No. CSV Preflight Desk does not guarantee an import into another system. QA Evidence Desk organizes your observations and supplied references. Campaign Test Planner calculates from your entered figures; it does not verify them or predict earnings.

What if I cannot download or open the file?

Use Contact Shop on the BOOTH listing and name the product, browser and visible error. Do not send passwords, private customer files or payment details. Confirm you are using the account that made the purchase, then download and unzip the complete ZIP.

About the maker

Yudai Shintake
Independent creator in Japan

I build small tools and reproducible examples for practical work. The sample inputs here are fictional. The four CSV files above are actual outputs from the browser trial, so you can inspect the decisions rather than relying on a performance claim.

These are original products made with AI assistance. They are independent of Google, Shopify and the marketplaces. For product-access questions, contact the shop through the relevant BOOTH listing.
