bash
togo install togo-framework/import-export

The togo answer to Laravel Excel / django-import-export: export any rows or a registered resource to CSV/XLSX, and import from CSV/XLSX with column mapping, header detection, and per-row validation that reports row/column errors instead of failing the whole file.

Usage

Export

go
ie, _ := importexport.FromKernel(k)

rows := []map[string]any{{"id": 1, "name": "Alice"}, {"id": 2, "name": "Bob"}}
csvBytes,  _ := ie.Export(ctx, rows, importexport.ExportOpts{Format: "csv",  Columns: []string{"id", "name"}})
xlsxBytes, _ := ie.Export(ctx, rows, importexport.ExportOpts{Format: "xlsx", Sheet: "People"})

Import (mapping + validation)

go
data := []byte("Identifier,Full Name\n1,Alice\n,Missing\n")
rows, rowErrors, err := ie.Import(ctx, data, importexport.ImportOpts{
    Format:  "csv",
    Mapping: map[string]string{"Identifier": "id", "Full Name": "name"},
    Validate: func(row map[string]any) error {
        if row["id"] == "" { return errors.New("id is required") }
        return nil
    },
})
// rows = valid rows (mapped to id/name); rowErrors = []RowError{ {Row:2, Message:"id is required"} }

Registered resources

go
importexport.Register(importexport.Resource{
    Name:    "people",
    Columns: []string{"id", "name"},
    Fetch:   func(ctx context.Context) ([]map[string]any, error) { return loadPeople(ctx) },
    Insert:  func(ctx context.Context, row map[string]any) error { return savePerson(ctx, row) },
})
// then export/import by name via the Go API or REST.
