Repeated CSV export checks: optional local workflow and feedback

[theluckystrike]

For people using this project's spreadsheet tools to prepare repeated CSV exports, there is an optional local rule-check workflow guide and free browser demo.

The demo checks two CSV snapshots against the limits you choose:

• Maximum number of added rows.
• Maximum number of removed rows.
• Maximum absolute price increase for each matched key. Price decreases are allowed; equality with the increase limit passes.

It accepts UTF-8, comma-separated CSV, at most 1,000,000 bytes and 5,000 data rows per file. Both files need identical ordered headers and one exact, unique, nonempty row key. Prices must be nonnegative plain decimals. Your files and rule values stay in the demo's browser; they are not carried over from this MCP server.

This checks the rules you supplied. It does not map supplier columns, validate Shopify or WooCommerce import behavior, write to a store, or guarantee import safety. Use the free demo to establish whether this narrow scope fits before considering any future pack. No seller call or bespoke setup is needed for the supported routine.

The guide also describes a separate proposed finite offline Node CLI pack at USD 7 once. The browser performs the same rules for free; the proposed pack's value is a reusable local bundle and saved-policy CLI workflow. It is not included in this project's MCP Pro license. No LIVE checkout, payment or preorder is available. Optional confirmed interest in the demo does not authorize a charge.

If useful, share which situation applies in this discussion:

1. I would repeat these exact checks on later exports.
2. I need a one-time comparison; the free browser is enough.
3. I need mapping, different formats, compound keys or actual import validation instead.

Feedback is voluntary and does not require a call or a purchase. Please share only a general workflow or public column names, not CSV files, confidential prices, personal data, credentials or payment details. These replies are workflow feedback, not orders or verified willingness to pay.
