Local file

Analyst Studio’s local file integration allows you to upload data directly from your computer into Analyst Studio datasets. This is the fastest way to perform ad hoc analysis on .csv, .tsv, and .xlsx files without requiring a cloud-based connection. You can then refine the data in the Spreadsheet view and publish it to the Data workspace for use in Liveboards and Spotter.

Requirements

Before you get started, ensure your file meets the following criteria:

Supported formats

.csv, .tsv, and .xlsx

File size

Files must be under 250 MB.

Prepare your local data

Following these guidelines ensures a clean, successful import:

Clean your data

Remove any empty rows or columns at the end of your file before uploading.

Date formats

Ensure date columns follow a consistent format (for example, YYYY-MM-DD) for accurate auto-detection.

Encoding

For .csv and .tsv files, use UTF-8 encoding to avoid character display issues.

Create a local file dataset

To create a new dataset:

  1. Click Create in the top right corner of your Analyst Studio home screen and choose Upload external data in the Datasets section.

    Click Create

    Alternatively, navigate to My Work, click Create in the top right corner, and choose Upload external data.

Define headers

Once you select a file, you are prompted to declare the header structure.

Are column names defined in first line?

If the first row contains column names, select Yes. If your file starts directly with data, select No.

Define headers

If you select No, Analyst Studio automatically identifies data types from the first row and generates generic column headers (for example, Column 1).

Review and refine columns

After the file is processed, a configuration modal appears. This allows you to verify the data before the dataset is created.

Dataset name

Enter a unique name for your dataset.

Dataset description

Add a description.

Data preview

View the first five rows of your data as a sample.

Column selection

Uncheck any columns you do not want to include in your dataset to save on processing and storage.

Data type assignment

Analyst Studio automatically parses and assigns data types (String, Number, Date, and so on).

Data type assignment

Modify data types and typecasting

You can override the auto-detected data types using the dropdown menu in the review modal. Changes must follow valid typecasting logic:

Compatible casting

You can change a Number to a String, or a Date to a Datetime.

Incompatible casting

You cannot cast String data (for example, Product A) to a Numerical or Boolean type. If a type change is invalid, an error message appears explaining the reason.

Edit your local file dataset

After your file data is uploaded, you can do the following from the Data view:

  • View the columns generated from the file in the Data tab.

  • View a list of all available fields in the Fields tab.

  • Open the dataset in the Spreadsheet view to manipulate the data — cleaning, formatting, and adding calculated fields — before publishing.

Publish your local file dataset

To publish the dataset to the Data workspace:

  1. Click Publish in the top right corner.

  2. In the Publish to the Data workspace window, enter the dataset name and click Publish.

The dataset is published as a table and can be consumed by Liveboards and Spotter.

Any manual or scheduled sync automatically republishes the dataset to the Data workspace.

For detailed publish and republish dependency behavior, see Reusable datasets.

Describe the fields in your dataset

Adding field descriptions helps build shared understanding around business logic, especially for ad hoc data where context can be lost.

To add a description:

  1. Open the dataset and navigate to the Fields tab.

  2. Double-click the row (field) you want to edit and add the description.

Descriptions support up to 350 characters and basic text formatting.

View source information

To see details about the original file used for the dataset, navigate to the Source tab. This displays the file name, file type, upload date, and the user who performed the upload.

Update your dataset’s name and description

You can change the dataset name or description at any time by clicking the name in the header area of the Dataset view. This does not affect the underlying data.

Schedule a local file dataset

Local files are point-in-time snapshots from your computer and do not support automated refresh scheduling. To update the data, you must perform a manual refresh by re-uploading the file.

Move a local file dataset to a Collection

By default, new datasets are saved to your My Work area. To share your analysis with others:

  • Open the dataset, click Move to a Collection, and select the appropriate team folder.

  • Alternatively, click the More icon, select Move to…​, and select the Collection.

    Move a local file dataset to a Collection

View a local file dataset

You can view your dataset at any time from the Datasets tab in My Work. The view provides a summary of the row count, column count, and last updated timestamp.

Use your local file dataset in a Report

Once the upload is complete, a success notification appears. Click Start Analysis to immediately open the Chart Builder and begin visualizing your data in a new Report.

Refresh data in a dataset-based Report

To update a Report built on a local file:

  1. Navigate to the dataset source.

  2. Select Refresh data.

  3. Upload the new version of your file.

The new file must have the same column structure (names and types) as the original to prevent Report breakage. If the dataset is published to the Data workspace, a successful sync also automatically republishes the data to the Data workspace.

Dataset permissions

Access to the dataset is determined by where it is stored:

Personal

Only you can view or edit datasets in your private workspace.

Collection

If the dataset is moved to a Collection, access is governed by the Collection’s permission settings (Viewer, Editor, or Manager).

Frequently asked questions

Can I change a .csv file to an .xlsx file during a refresh?

Yes, as long as the internal data structure and column headers match exactly.

What happens if my file has merged cells?

Merged cells can cause data alignment issues. Unmerge all cells and fill them with values before uploading.

Is there a limit to how many local files I can upload?

There is no limit on the number of files. However, your total Workspace storage limit, as defined by your admin, still applies.
