What Is Impler?
Impler is an open-source CSV import tool designed for basic integration needs. It allows users to upload CSV files, map columns manually, and validate imported data.
Key features of Impler:
- Open-source core, with optional hosted versions
- Manual column mapping interface

The CSV Import Flow: file → map → validate → submit
A reliable import experience follows a clear flow. Whether you use Impler, CSVBox, or another importer, think in terms of these steps:
- File: Accept CSV/TSV/XLSX uploads and surface file parsing errors (encoding, delimiters).
- Map: Let users map spreadsheet columns to your application fields (with previews).
- Validate: Apply schema-based rules (types, required fields, regexes) and report row-level errors.
- Submit: Accept the cleaned data, provide audit logs or import history, and trigger webhooks or background processing.
Focusing product and engineering effort on these stages reduces support overhead and creates predictable onboarding for non-technical users.
