Dromo is an intuitive spreadsheet importer that integrates seamlessly with your product, enabling users to match columns, correct errors, perform complex validations, transform values, and upload perfectly formatted data.
Dromo is an intuitive spreadsheet importer that integrates seamlessly with your product, enabling users to match columns, correct errors, perform complex validations, transform values, and upload perfectly formatted data. On Nagent, Dromo is exposed as a fully-configurable spreadsheets integration that any agent can call — 8 actions, and API key authentication. No code is required to wire Dromo into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Dromo to automate the kinds of tasks spreadsheets teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Dromo into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Dromo, with input parameters and output schema. Drop these into any step of an agent built in Helix.
DROMO_CREATE_HEADLESS_IMPORTTool to create a headless import in Dromo. Returns a signed upload URL for file uploads. Use this before uploading files to obtain the temporary upload URL.
Input parameters
UUID of the saved schema defining data structure and validation rules
JSON string containing array of objects to import directly instead of uploading a file

Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_CREATE_IMPORT_SCHEMATool to create a new import schema in Dromo. Define fields, validation rules, and settings for data imports. Use this when setting up a new data import workflow or template.
Input parameters
Name of the import schema for identification and display
Webhook configuration for various import events.
Array of field definitions that define the structure and validation for imported data. Must contain at least one field.
Configuration settings for the import schema behavior and appearance
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_DELETE_IMPORT_SCHEMATool to delete an import schema in Dromo. Use when you need to remove a schema definition that is no longer needed. This action is irreversible.
Input parameters
UUID of the import schema to delete
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_GET_IMPORT_SCHEMATool to retrieve an import schema by ID from Dromo. Returns the complete schema definition including fields, validation rules, settings, and webhook configurations. Use this to inspect schema structure, validate field requirements, or retrieve configuration details before creating imports.
Input parameters
Unique identifier of the import schema to retrieve
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_LIST_IMPORT_SCHEMASTool to retrieve all import schemas configured for your Dromo organization. Use this to discover available schemas, their field definitions, validation rules, and settings before creating imports.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_LIST_UPLOADSRetrieves a paginated list of all file uploads stored by Dromo for your organization. Returns upload metadata including status, row counts, errors, user information, and file details. Use this to monitor import progress, track upload history, or retrieve upload IDs for further processing.
Input parameters
Ending index for pagination (exclusive). Must be greater than start. Defaults to 10000. Maximum value is 10000.
Starting index for pagination (inclusive). Defaults to 0.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_UPDATE_IMPORT_SCHEMATool to update an existing import schema in Dromo. Modifies the schema definition including fields, validation rules, and settings. Use when you need to change field configurations, add/remove validators, or update import settings for an existing schema.
Input parameters
UUID of the import schema to update
Display name for the import schema
Webhook configuration for various import events.
List of field configurations defining the schema structure
Configuration settings for the import schema
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
DROMO_UPLOAD_FILE_TO_HEADLESS_IMPORTUpload a file to Dromo's headless import system using a presigned S3 URL. This action performs the actual file upload step in Dromo's headless import workflow: 1. First, create a headless import via POST to /headless/imports/ to get an upload URL 2. Then, use this action to upload the file to that URL 3. Dromo automatically processes the file once the upload completes The upload URL is valid for 30 minutes. This action performs an HTTP PUT request with the file content to the provided presigned S3 URL.
Input parameters
Raw file content as bytes. For CSV files, encode the CSV text as UTF-8 bytes. For binary files, provide the raw binary data.
Presigned S3 URL obtained from creating a headless import. This URL is valid for 30 minutes and grants temporary permission to upload the file via HTTP PUT. Obtain this URL by creating a headless import with the Dromo API.
MIME type of the file being uploaded. Common values: 'text/csv' for CSV files, 'application/vnd.ms-excel' for Excel files, 'text/plain' for text files.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 45 agents privately built on Nagent that already use Dromo.
Build on Nagent
Connect Dromo to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Dromo, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Dromo is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Dromo is connected, you configure its 8 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Dromo steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Dromo event fires, the agent kicks off automatically.
Every Dromo action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Dromo ships with 8 pre-built spreadsheets actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Dromo together with other connected tools.
