Export

The Export section lets you export documents from a collection to various file formats.

Formats

Mingo supports exporting to:

• CSV / TSV — comma or tab-separated values, useful for spreadsheets
• JSON — standard JSON format
• JavaScript Objects — JavaScript object notation (unquoted keys)
• BSON — binary JSON, MongoDB's native format

CSV Options

When exporting to CSV/TSV, customize:

• Row separator — line ending format
• Column separator — comma, tab, semicolon, or custom
• Value wrapper — quoting style for values
• Include headers — toggle header row

Column Mapping

Define custom columns using JavaScript expressions. Each column has access to:

• doc — the current document
• _ — Lodash utility library
• dayjs — date manipulation library
• ObjectId — MongoDB ObjectId

This lets you transform values, combine fields, or format data during export.

Filtering

Apply filters before exporting:

• Selector — query filter to export only matching documents
• Sort — order of exported documents
• Skip / Limit — control the range of documents

Export Destinations

• File — save to a file on disk
• Clipboard — copy directly to clipboard

Saved Exports

Save export configurations per collection for reuse. This is useful when you regularly export data in the same format.
