Free check · your CSV copy · up to 20 products

Check a small copy of your product CSV before buying.

Open a CSV copy with up to 20 products, select its first 20 products below, or paste a small table copied from Excel. Choose the text format explicitly, connect five fields, then check. XLSX files are not read.

The file is read only in this browser’s memory. Neither the file nor its contents are sent, stored or used for analytics. Clearing the input or refreshing removes them. Do not enter orders, customer details, passwords or confidential data.

Choose the encoding used when saving the CSV. It is not detected automatically. Check the displayed product names before mapping columns.

No checks yet. Paste CSV text and read its columns.

Free: up to 20 products and text up to 32 KiB in UTF-8; no report export. Open a 32 KiB CSV copy, or explicitly select the first 20 products from a copy up to 2 MiB. The paid tool checks up to 1,000 products in UTF-8/CP949 CSV files and saves CSV/TXT reports. Korean and English interfaces and guides are included.

Preparing a WooCommerce import? Review a simple-product CSV copy free. The general checker excludes decimal prices. The included separate English simple-product companion reviews decimal-price text; variants and full import acceptance remain outside scope.

Contents and purchase conditions

What is included?

Repeat checks on your own product CSV

Map five fields, review errors, warnings and affected rows, page through 20 issues at a time, and save CSV or TXT reports. Recommended browser: Windows Edge.

A self-contained download

Extract the ZIP, then open Start-English.html or 시작.html. English/Korean guides and the original fictional UTF-8/CP949 examples are included. No installation, account or cloud file transfer is required.

The demo is self-created. It is not a client delivery, a Make integration or evidence of customer results. This same paid ZIP is offered on both language pages. Korean and English interfaces share the original validation engine, limits and purchase conditions.

Before you buy

Which languages are included?

The ZIP contains 시작.html (Korean), Start-English.html (English), both usage guides and the original Korean example files, plus Start-WooCommerce-English.html and its English/Korean guides. Map Korean headers manually in the English interface. Live English support and custom file review are not included.

Which CSV files can it check?

Comma-separated CSV with a header row, UTF-8 (with or without BOM) or CP949, up to 1,000 product rows, 100 columns and 2 MiB. The general checker uses non-negative integer prices/stock. The separate WooCommerce companion reviews decimal price text for Type=simple, with exact English headers and UTF-8 only. Variants/store matching/import acceptance are outside scope. XLSX, tab-separated files, semicolon-separated files and automatic encoding detection are not supported.

Can I use my own column names?

Map five columns to SKU, product name, price, stock and image URL. Only exact header matches are selected automatically; other names are not guessed. Unselected columns are not checked.

Does it fix or upload my original file?

It does not edit, merge, delete or upload the original. Read the row and reason in the report, correct a copy yourself, then check again. SKU values keep leading zeroes and are case-sensitive.

Does a clean result guarantee marketplace acceptance?

No. This is not a complete import-template validator for any marketplace. Check platform-specific categories, options, shipping fields and requirements separately. Image URLs are checked for format only; image availability and usage rights are not verified.

Is this a custom CSV cleanup service?

This purchase is a self-use downloadable tool. Manual file review, custom code, a Make scenario, marketplace upload and future feature development are not included. Do not enter order, member or customer personal information.
