Questions & Answers

As answered by people managing MapMyCSV and Flatfile.

How would you describe the primary audience of your product?

MapMyCSV's answer

MapMyCSV is for operations teams, administrators, bookkeepers, implementation consultants, and SaaS teams who regularly move data between systems. Typical uses include reshaping exports for CRM, accounting, ERP, HR, email-platform, and database import templates.

Which are the primary technologies used for building your product?

MapMyCSV's answer

React, TypeScript, Vite, Papa Parse, and native browser File, Blob, download, and local-storage APIs. MapMyCSV is a static client-side application hosted on Cloudflare Pages; CSV contents are not sent to a backend.

What makes your product unique?

MapMyCSV's answer

MapMyCSV maps a messy source CSV into any target import template entirely inside the browser. It combines automatic header matching, manual overrides, date normalization, row-level validation, and an import-ready export without uploading the CSV, requiring an account, or charging a subscription.

Why should a person choose your product over its competitors?

MapMyCSV's answer

Choose MapMyCSV when you need to fix a CSV import without buying a full data-integration platform or uploading sensitive data to a conversion service. It is focused on one job, works locally in the browser, provides a free mapped preview, and unlocks full exports for a one-time $29 payment rather than a recurring subscription.

What's the story behind your product?

MapMyCSV's answer

MapMyCSV came from a recurring operations problem: the source data was available, the destination provided an import template, and the two CSVs almost matchedโ€”but the headers, dates, names, and column order were different. Every import became another round of spreadsheet surgery. MapMyCSV was built as a focused, private way to complete that mapping in the browser without uploading customer, financial, employee, or operational data.
