Before buying a CSV tool
Prepare a CSV copy
Use comma-separated CSV with a header and the stated encoding and size limits. XLSX and VCF are not read directly. Source headers and values stay in their original language.
Use the trial to check fit
Confirm column mapping and the meaning of the result before buying. Trial limits differ from the paid downloads. The free Google-header assistant is separate from the contact ZIP.
Check your operating environment
Extract the paid ZIP and follow its Windows Edge guide. Direct file opening, actual customer files, Excel/CRM imports and mobile use remain unverified. No n8n installation, database connection or store upload is included.
Files used in the free tools stay in your browser. This page has no upload or enquiry form. Optional visitor analytics follows the separate consent choice; CSV contents and file names are excluded. English custom cleanup support is not included.
Existing product CSV conditions (English) and contact review conditions (English) apply. Order, file-access and refund enquiries follow the existing Lemon Squeezy order/support route.
Building a staff-managed WordPress catalog?
The existing WordPress travel and study catalog developer starter is KRW 29,900, one time. It supplies theme and plugin installation ZIPs, full GPL sources and installation/staff handoff documents for developers with PHP/CSS skills.
The visitor interface and documents are in Korean. Browse the existing fictional read-only preview (Korean) before reading the files, editing limits and checked environment. Installation service, booking, payment and ongoing support are excluded.
Planning an import or comparing two copies?
For a Make scenario handoff, see the read-only report and owner-check sample and the existing conditional USD35 proposal. No import, execution or production repair is included.
Before sending selected fields into n8n or a database, use the free CSV column-selection plan to record required destinations and empty-cell handling. It saves a planning note, not a workflow, and does not connect to a database.
Free two-copy CSV comparison helps review added, removed and changed rows. It is separate from these paid downloads. For Google exports, start with the free Google contact column guide.
For HubSpot, check blank Record IDs and selected email coverage locally before importing. It does not certify an update or look up your account.
For a separately scoped automation handoff, inspect two local n8n execution examples. These synthetic demonstrations are separate from the paid CSV downloads and do not establish customer delivery or database insertion.
Updating Salesforce Contacts from a CSV?
Review repeated emails alongside the original Contact IDs. Keep Account IDs separate, choose the actual matching method in Salesforce and try the local 20-row check before choosing the existing report download.
Preparing a Mailchimp CSV update?
Review repeated emails and conflicting profile values before importing. Keep audience and contact-type context and try the existing source-preserving check locally before choosing a download.
