ET1 Constant Node

by tyler garrett | Sep 19, 2025 | App Documentation

The Constant Node creates a constant value per row in your data pipeline.

This node is extremely handy when transforming data in your ETL processes.

The Constant Node is rather straight forward, two inputs and you’re done.

Using the Constant Node

Add the Constant Node to your canvas, send data downstream to your node and open the settings.

edit the constant column name or keep it default “const”
add a value

The Constant Node highlights the constant column so that you’re able to easily identify the additional column.

Using the Constant Node

Sending the City, State data from the CSV Input Node to the Constant Node and adding “USA” as the Value, and “Country” as the Column header.

We would love to hear about your solutions.

ET1 Concat Node

by tyler garrett | Sep 19, 2025 | App Documentation

Bring your columns together as one with the Concat Node in ET1.

This node is similar to concat() in Excel and allows you to easily bring more than 1 column together in your data pipeline, and also it gives you the ability to add the delimiter. The opposite of the Concat Node is the Split Node.

How to use Concat Node in ET1

Simply send data to the Concat Node and start setting up your node.

choose columns
choose separator
output column name
keep original columns (yes or no)

In this example we have Location and Supplier column that needs to be put together and removed from our data pipeline. By default the Concat Node calls the new column concatenated, and might be helpful for early adopters to remember what happened in this column. However our boss asked us to change headers and concat data in their CSV data.

We use the CSV Input Node. Although the Column Renamer Node may help, we wanted to consolidate your effort here incase renaming the header is ideal.

The Concat Node has 4 different settings, and help end users clean up their concatenation efforts. You may or may not want original columns and this is an important element to consider.

ET1 Find/Replace Node

by tyler garrett | Sep 18, 2025 | App Documentation

Automatically finding and replacing data is possible using the Find/Replace Node!

Find and replace works inside of sentences, words, numbers, and anywhere in the data.

Similar to “find all” and “replace all,” in your common Word Document software, ET1 offers the same but in a repeatable and consistent data app.

Using Find/Replace Node

Finding data you want to edit and replacing this automatically can be a lot of work, and with ET1’s Find/Replace Node, it’s easy to repeat.

Send data downstream to ET1’s Find/Replace Node
Select a column
Type what to find
Type what to replace
Determine if Case sensitive matters
Decide if you’re going to use regex (advanced but worth the effort)
Match the entire cell to consider it replaceable

Quick example of Find/Replace Node

In this example we have city/state data from our CSV Input Node, this data can be found in our Github CSV Node overview.

This data is City, and Short State.

Perhaps we wanted to swap MA short state with Meow to amuse our boss for 1 second.

ET1 Manual Table Node

by tyler garrett | Sep 18, 2025 | App Documentation

Create a table manually using the Manual Table Node. Manual Table node falls under the data input node category.

Built to help you create small tables that you need to use in your data pipelines.

When you need a thin layer of data, this is a great tool for manually synthesizing your data which happens to occur regularly while creating ETL processes.

We like to think of the Manual Table Node as a building node, for storing important variables, or simply creating data from scratch without requiring a file or data pipeline established.

Using the Manual Table Node

Using the Manual Table Node is straight forward in ET1.

type in headers for column 1 and/or column 2
begin creating the first row of data
add more rows or delete rows

ET1 Github CSV Node

by tyler garrett | Sep 18, 2025 | App Documentation

ET1’s Github CSV Node is designed to help end users extract data from Github CSV URLs which are in public repositories.

A public repository on Github is not a place to put your private or company information. However City/State for USA is a commonly used resource in Map Data related solutions.

Unlike the CSV Input Node, which reads data local on your computer, the Github CSV Node is online data.

Any CSV file online is accessible for extraction with this node, if it’s a functional CSV file.

Quick Start

Paste a link to a CSV. We use Github because it’s a familiar repository for engineers and organizations.

https://raw.githubusercontent.com/MassiveNoobie/ET1_PUB/refs/heads/main/City-ShortState-USA.csv

If you have a link to github csv public repository, you’re ready to get started.

If you need an example, use the following tutorial below.

Finding Github CSVs for your ETL process

Start with www.google.com, search idea:

<Insert the data source you need> + “Github CSV” would be the best bet.
However github isn’t a requirement

Example: I found state/city data by googling and then:

Googling “City State Github CSV”
Then you’re taken to a page like this screenshot below
Click RAW..

Clicking RAW drives you to “githubusercontent”.”com”…. Here is where you’re going to grab the URL.

This URL will be pasted in your ET1 Github CSV Node. The screenshot below is what the CSV looks like on Github and what the URL looks like that you’d need to capture. A URL with “.csv” is ideal.

Using Github CSV Node

Extracting data from the Github CSV Node only requires a link, use the one above.

Follow instructions above to find the URL
Paste the URL, Github CSV Node will fetch data automatically
Fetch button: created to “refresh”
This node will work for any public facing CSV endpoint
- we hope, not all CSV files are created equally

In this example we are pulling data using the Github CSV Node, and writing the data to a file using the CSV Output Node.
