Dataset Merge, Dedupe & Transform (datasets, JSON, CSV)

Dataset Merge & Dedup Datasets — Filter, Join CSV & Excel

saliga/dataset-merge-dedupe

Merge Apify datasets, CSV, JSON and Excel files or Google Sheets into one table. Clean fields, normalise URLs, extract domains, filter, remove duplicates and join (VLOOKUP) in one run. Works with limited permissions. CSV and Excel exports free. $0.50 per 1,000 output rows.

Dataset Cleaner & Exporter

nerolabs/dataset-cleaner-exporter

Returns a deduplicated, flattened and cleaned copy of any Apify dataset, file or Google Sheet by URL, or JSON array, plus CSV and Excel files, named-dataset append and webhook delivery. Inputs: source, dedup keys, flatten, cleaning options. Agent-ready: pay per event (x402, MCP), per cleaned record.

Utility actor that allows you to build a single large dataset from individual default datasets of other actor runs.

Deduplicate, Merge & Transform Datasets

datacach/deduplicate-datasets

Merge multiple datasets, deduplicate items by a combination of fields, and apply custom transforms — powered by Polars.

Airtable (apify/airtable)

apify/airtable-apify-airtable

Imports any Apify dataset into Airtable with append, override, or create modes. Supports custom field mapping, automatic column creation, duplicate detection, batching, retries, and OAuth. Works standalone or as an Actor-to-Actor integration.

LLM Dataset Processor

dusan.vystrcil/llm-dataset-processor

Allows you to process output of other actors or stored dataset with single LLM prompt. It's useful if you need to enrich data, summarize content, extract specific information, or manipulate data in a structured way using AI.

Remove Duplicates & Merge Datasets: Dedup, Only New

brasspage/dataset-dedup-merge

Dedup and merge Apify datasets: removes duplicate items by any fields, or by the whole item, and returns the unique items (or only the duplicates) with their original fields. Can skip items seen in earlier runs, for daily new results. Works with limited permissions. $0.02 per 1,000 items.

JSON to CSV Converter

eloquent_mountain/json-to-csv-converter

JSON to CSV Converter. Effortlessly transform JSON data into CSV with our Apify actor. Handle nested structures, expand lists into rows, and customize separators and delimiters. Input via URL or paste JSON text. Ideal for data analysis and reporting!

Synthetic Dataset Generator

jungle_synthesizer/synthetic-dataset-generator

Generate realistic synthetic datasets with correlated fields, built-in presets (user profiles, companies, e-commerce products, log events), custom schemas, deterministic seeding, and multiple output formats (JSON, CSV, NDJSON).

Merge & Deduplicate Datasets - Reliable, Any Size

geese_chief/dataset-merge-dedup

Merge any number of Apify datasets into one and remove duplicates by the fields you choose (url, id, email...). Keep unique items or only the duplicates, pick output fields, tag each item with its source. Streams data, so millions of items work. Pick datasets from your storage: no permission errors.
