Parabola allows you to assign a batch number to each row using the Add row numbers step, and then filter and export those batches individually.

​
Basic Setup (manual splitting)

Steps:
1

Import your file

  • Use the Pull from Excel file or Pull from CSV file step to upload your dataset.
2

Assign batch numbers

  • Add an Add row numbers step.
  • Set it to repeat each number 20,000 times.
  • This will tag rows 1–20,000 with 1, 20,001–40,000 with 2, and so on.
3

Filter and export each batch manually

  • Add a Filter rows step for each batch (e.g., where “Row Number” = 1).
  • Follow it with a Generate CSV file step to export that batch.
  • Repeat for each batch needed.
Parabola can only export one CSV file per Generate CSV file step. Each batch needs its own export step.

​
Advanced Setup (automated batch export)

To automate this over time, especially for files received regularly: Steps:
1
Use a Parabola table to store the last processed batch number.
2
In each run:
  • Pull the large file and assign batch numbers as above.
  • Use a Find overlap step to match rows with the next batch number.
  • Export the batch using a Generate CSV file step.
  • Update the batch tracker in the Parabola table to increment the number.
3
Repeat runs until all batches are processed.
This approach simulates a loop without requiring manual edits every time the file changes.
