Features & Specs

  1. Browser-side processing

    Parsing, mapping, validation, and normalization run on the customer’s device. Spreadsheet contents are not uploaded to Bootstrapware.

  2. Column mapping

    Automatically maps headers using aliases. Users can manually remap columns, and preview remains blocked until all required fields are mapped.

  3. Typed validation

    Supports string, number, date, email, enum, boolean, URL, required, and field-level unique validation.

  4. File format support

    Supports CSV, XLSX, TSV, semicolon-delimited, and pipe-delimited files with automatic delimiter detection.

  5. Multi-sheet Excel

    Excel workbooks include a sheet picker so users can select the correct worksheet before mapping.

  6. Preview

    Displays counts for the complete file and previews the first 100 rows so users can identify problems before submission.

  7. Duplicate detection

    Detects case-insensitive duplicates using a configured duplicate key or fields marked as unique.

  8. Failed-row export

    Exports import-errors.csv with the original field columns and an Errors column for correction and re-upload.

  9. Localization

    Supports US and EU number formats, MDY or DMY dates, and left-to-right or right-to-left interfaces.

  10. Configuration revisions

    Teams can edit a draft without affecting live clients, then publish the new configuration when ready.

  11. Operational webhooks

    Sends HMAC-signed import.completed webhooks containing operational metadata, never spreadsheet contents.

  12. Downloadable templates

    Generates a template CSV in the browser using the configured schema and field examples.

Questions & Answers

As answered by people managing Bootstrapware Importer.
  1. What makes Bootstrapware Importer unique?

    Bootstrapware Importer provides a complete spreadsheet import experience while keeping customer data out of the vendor’s infrastructure. CSV, Excel, TSV, and other supported files are parsed, mapped, validated, and previewed directly in the browser. File contents, filenames, parsed rows, and normalized data never reach Bootstrapware. The host application receives validated objects through an onComplete callback and remains responsible for authorization and storage.

  2. Why should a person choose Bootstrapware Importer over its competitors?

    Bootstrapware Importer is designed for small production SaaS teams that need a reliable import workflow without enterprise data-onboarding complexity or pricing. It includes column mapping, typed validation, spreadsheet previews, duplicate detection, multi-sheet Excel support, downloadable templates, and failed-row export for $19.99 per month. Development and evaluation remain free, and spreadsheet data is processed entirely in the customer’s browser.

  3. How would you describe the primary audience of Bootstrapware Importer?

    Bootstrapware Importer is built for bootstrapped founders, independent developers, AI-assisted builders, and small SaaS teams whose customers need to import users, contacts, products, inventory, or other structured records from spreadsheets. It is best suited to React applications that need a polished production import flow without building and maintaining the entire interface internally.

  4. What's the story behind Bootstrapware Importer?

    Bootstrapware Importer was created around a simple observation: generating a basic CSV parser is easy, but operating a dependable customer-facing import workflow is not. Column mapping, messy spreadsheet formats, localized numbers and dates, validation, duplicate handling, previews, and useful error recovery create an ongoing maintenance burden. Bootstrapware packages those production details into a focused React component priced for small SaaS businesses.

  5. Which are the primary technologies used for building Bootstrapware Importer?

    Bootstrapware Importer is built for the modern React and TypeScript ecosystem and distributed as a typed npm package. Spreadsheet parsing and validation run through browser-side JavaScript, while the hosted control plane provides published configuration, production keys, operational session metadata, and webhooks. It works with React applications built using frameworks and tools such as Next.js, Remix, and Vite.
