Read table


This activity is used to read the contents of a specified table. Excel, Google Sheets and CSV tables are supported.

When adding this activity to a workflow, an 'Assign value to variable' action block connected to this block will also appear. The result of reading operation will be saved to this variable. That being said, this variable stores the table contents and provides a visual representation of the table data.

However, using the 'Assign value to variable' activity is not strictly necessary in this case. It is safe to delete this block and handle the result any other way. For example, it is possible to connect the 'Read table' activity to the 'For each row' activity and use the Save the previous step result option.

One more important thing to remember: in case your table is currently open in any desktop application, do not forget to close it. Otherwise, Studio will not be able to get access to the file and execute the activity.


The set of parameters depends on the chosen option: Excel, Google Sheets or CSV.

Read table from is the general parameter which defines what kind of table you are going to read. It is required.

Reading an Excel table works the same way as the separate 'Read Excel table' activity. Read about it in this article. Read Excel file

Google Sheets

If we choose to read a table from Google Sheets, we will see the following parameters.

The first one here is Google account. It is required to connect the account where the table is stored. If you have not done this yet, this is what you will see here.

This message shows that the Google account is not connected

Click the link in this message. The settings menu will open. Here you will be able to login to your Google account and connect it. Click the 'Authenticate' button to do it.

The 'Services' menu where you can login to your account

Once it is done, you should see this message. It indicates that you can use the table stored in your account.

The next parameter is Spreadsheet Id. It is used to specify the table itself. Pay attention to the tooltip that appears when hovering your cursor over the input field: it is only required to input the ID of the table, not the whole link. This is a required parameter.

For example, if the link is, then the ID is 11sw2l2a6b1n2l8aDP_E9_SjAV.

The last parameter is Range. It defines what part of the table needs to be read. There is also a tooltip for it. This is a required parameter.

The only parameter here is Path which lets you specify the needed .csv table file. Use the 'Pick' option to choose the file using Explorer. This is a required parameter.

Studio Pro supports auto recognition of such delimiters as ,, ; and tab. Regardless of the chosen delimiter, the data from the table will be read in the exact same way.


In this case we used the 'Assign value to variable' activity to save and display the results.

For each row


This activity makes it possible to apply a set of actions to each row in the specified table.

It has a special structure. When added to a workflow, a gray region will appear. It contains the body of the loop (i.e. the set of actions you are going to perform). Drag and drop the desired activities here and connect them with the activity block itself and the 'Loop end' block.

This is how a newly added block looks like.


Let us start with an example of a workflow that has this activity. Here we read the contents of the table, save it to a variable and output the contents by each column to the console.

These 'Console log' blocks are responsible for displaying the output. Each block displays one column of the table. Here is an example of how they are set.

This 'Console log' block outputs the contents of the 'Name' column. Others display 'Surname' and 'Age' columns and are set similarly


Now let us review the parameters of the activity based on the shown example.

Table parameter defines the source table itself. imported_table is the name of the table that we have read.

It is worth mentioning that this activity is best to use in conjunction with 'Read table'. In that case, if 'For each row' is placed right after 'Read table', then you do not need to save the table content to a variable and you can leave the Save the previous step option enabled.

Template table defines the table (an .xls or .xlsx file) that will be used as a template to automatically generate the column variables. It is possible to either pick the same table you have already read or create a separate one. This is done to just generate the variable names for the columns.

This is how the template table looks in our case.

Variables parameter defines what will be used for the names of the column variables: table headers as specified in the template table or plain letters.

Here we can view them. Column header and column name are the same because we have chosen the Use table headers option. The variable names are editable.

If the Use column letters option is selected, then the Name, Surname and Age headers will be replaced with A, B and C respectively.


Here is the output we have received. Each 'Console log' block displays one column (name, surname and age variables).

Remove empty rows


Removes all empty rows from a table.



  • Save the previous step result: take the previous step result to get a variable that contains a table.
  • Calculate a value: use JS to get a table.


  • Each cell in a row is empty: removes all rows with all empty cells.
  • At least one cell in a row is empty: removes all rows with at least one empty cell.

Usage Examples

This activity helps to filter your table and remove all empty rows.
