DEPRECATED: This endpoint has been deprecated and will be removed on March 1, 2026. Please use the new endpoint: POST /v1/uploads/csvSee the Migration Guide for details on migrating to the new endpoints.
Consider using the /create and /insert endpoints if you want more flexibility, performance, and the ability to append.
You can also upload CSV through the Dune UI by pressing the “create” dropdown.
For working with uploads, keep in mind that:
  • File has to be < 200 MB
  • Column names in the table can’t start with a special character or digits.
  • Private uploads require a Premium subscription.
  • If you upload to an existing table name, it will delete the old data and overwite it with your new data. Appends are only supported for the /create, /insert endpoints.
  • To delete an upload table, you must go to user settings (dune.com) -> data -> delete.
If you have larger datasets you want to upload, please contact us here

Upload via google sheet

To automate the upload of a Google Sheet’s contents to Dune via API, use the following Google Apps Script: 
function uploadToDune() {
  var apiKey = "YOUR_DUNE_API_KEY"; // Replace with your actual Dune API key, keep the quotes
  var tableName = "example_table"; // Update with your desired table name
  var description = "Example table description";

  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var range = sheet.getDataRange();
  var values = range.getValues();

  // Convert data to CSV format
  var csvData = "";
  for (var i = 0; i < values.length; i++) {
    csvData += values[i].join(",") + "\n";
  }

  var payload = {
    data: csvData.trim(),
    description: description,
    table_name: tableName,
    is_private: false
  };

  var options = {
    method: "post",
    contentType: "application/json",
    headers: {
      "X-DUNE-API-KEY": apiKey
    },
    payload: JSON.stringify(payload)
  };

  var response = UrlFetchApp.fetch("https://api.dune.com/api/v1/table/upload/csv", options);
  Logger.log(response.getContentText());
}
Steps to Use:
  1. Open your Google Sheet
  2. Navigate to Extensions → Apps Script
  3. Replace the script with the code above
  4. Save and run uploadToDune
  5. (Optional) For easier execution, you can assign this script to a button in your Google Sheet:
    • Click “Insert” in the Google Sheets menu
    • Select “Drawing”
    • Create a button shape and add text like “Upload to Dune”
    • Click “Save and Close”
    • Right-click the button and select “Assign script”
    • Enter “uploadToDune” as the function name
  6. Clicking the button will now upload your active sheet’s data to Dune!
