Data managers moving into or syncing with Odoo hit the same wall every migration cycle: the native Import tool is stateless. You rebuild the column-to-field mapping by hand for every file, re-tick "Don't import" on the same junk columns, and re-explain to a colleague which sheet feeds res.partner versus product.template. When a load half-fails, Odoo aborts the batch with a single terse error instead of telling you which of the 4,000 rows was bad. There is no way to save a mapping, no way to transform values on the way in (trim, upper-case, map "Yes/No" to booleans, look up an external ID), and no way to run the same export on a schedule. For teams doing repeated onboarding, multi-entity consolidation, or nightly syncs, that native ceiling turns a five-minute job into an afternoon.

Advanced Import / Export Templating is a build-to-order Odoo module that turns those one-off mappings into first-class, reusable records. We add an ir.import.template model (and matching export template) that stores the target model, the column-to-field mapping, per-field transforms, and validation rules as saved configuration you name once and reuse forever. Mappings target any model in the registry — including your custom addons — and support related fields via parent_id/name dot-notation and external-ID resolution (__export__/XML IDs) so relational links resolve correctly instead of failing silently. Transforms are declarative (trim, case, date-format normalization, default-on-empty, regex replace, boolean/selection value maps) with a hook for a Python expression when a client's data is genuinely messy.

Technically, the module is a clean Odoo addon: a proper __manifest__.py, models built on models.Model with fields and @api.depends computes where derived state is needed, an OWL/XML wizard for the upload-preview-validate-commit flow, and ir.model.access.csv plus record rules so template ownership and execution are permission-scoped (import/export can be gated by group). Validation runs in a dry-run pass first: every row is checked against field types, required fields, selection domains, and your custom rules, and failures are collected into a downloadable error-row report (row number, column, value, reason) rendered via a QWeb report — so you fix the source file, not guess. Both CSV and XLSX are supported on read and write. Recurring jobs are wired through ir.cron / automated actions so a template can pull a file from a configured location (or push an export) on a schedule, and every run is logged. The same templates are callable over XML-RPC / JSON-RPC, so an external ETL or another system can trigger a validated load programmatically.

Because this is build-to-order, ECOSIRE builds the module against your exact Odoo version (17.0, 18.0, or 19.0), your edition (Community or Enterprise — we note where Enterprise-only fields or studio models affect mapping), and your real target models and file formats. We start with a short scoping call to confirm the models, the transforms your data actually needs, and where scheduled files land. Typical delivery is 2-4 weeks from confirmed scope. You get installable source, a UAT pass on your staging database with a rollback plan, documentation, a training session for your data team, and a post-go-live support window — not a black-box zip.
