# Jupyter Notebook to Reproducible Script Linearizer Turn .ipynb into a # %% Python script and detect out-of-order, hidden, and deleted state > Canonical page: https://elysiatools.com/en/tools/jupyter-notebook-to-reproducible-script-linearizer - **Category:** Data Processing - **Keywords:** Jupyter, ipynb, notebook, reproducibility, Python script, cell order, hidden state, nbconvert ## Overview Linearizes code by execution_count or document order and statically checks use-before-definition, mutable cross-cell state, references after deletion, random seeds, file paths, environment dependencies, and notebook magics. ## Inputs - **Notebook Input** (textarea): Paste the JSON content of an .ipynb file - **Notebook File** (file) - **Cell Order** (select) - **Include Markdown as comments** (checkbox) ## When to use - Review a notebook that only runs correctly after cells are executed out of order. - Create a linear Python script for inspecting notebook code and cell dependencies. - Find reproducibility risks such as use-before-definition, mutable cross-cell state, paths, seeds, and notebook magics. ## How it works - Paste the JSON content of an .ipynb file or provide a supported notebook file. - Choose Execution order to follow execution_count values or Document order to follow the notebook layout. - Choose whether Markdown cells should appear as comments in the generated script. - The tool returns linearized Python and a report covering detected state and environment-related risks. ## Use cases - Audit exploratory data analysis notebooks before sharing them with teammates. - Inspect machine learning notebooks that depend on hidden execution state. - Prepare notebook code for reproducibility reviews by exposing cell order and cross-cell references. ## Frequently asked questions ### What input does the tool accept? It accepts pasted .ipynb JSON or a notebook file using supported JSON or plain-text MIME types. ### How are notebook cells ordered? Cells can be ordered by execution count or by their document order. ### Does the output include Markdown cells? Yes, Markdown can be included as comments when the option is enabled. ### What reproducibility issues can it detect? It checks for use-before-definition, mutable cross-cell state, references after deletion, random seeds, file paths, environment dependencies, and notebook magics. ### What does the tool produce? It produces text containing a reproducibility report and a linearized Python script with # %% markers. ## Related tools - [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown - [CSV to Database Migration Planner](https://elysiatools.com/en/tools/csv-to-database-migration-planner): Infer a relational schema from CSV data and generate create-table plus ALTER migration plans for PostgreSQL, MySQL, SQLite, or SQL Server - [Encrypted PDF Converter](https://elysiatools.com/en/tools/encrypted-pdf-converter): Open password-protected PDFs with OpenDataLoader and export them as Markdown, JSON, or text once the correct password is provided - [OCR PDF to Structured JSON Bridge](https://elysiatools.com/en/tools/ocr-pdf-to-structured-json-bridge): Extract the PDF text layer with geometry (lines by y-position, tables by column gaps, headings by font size, colon key-value pairs), then fill a user-supplied JSON Schema field by field — labels matched by normalized keys, values coerced to declared types and validated with ajv. - [Podcast Chapter Marker Builder](https://elysiatools.com/en/tools/podcast-chapter-marker-builder): Build every podcast chapter format from one timecoded list: Podcasting 2.0 JSON + RSS tag, ID3v2.4 CHAP+CTOC burned into an MP3, Vorbis comments, mp4chaps, YouTube timestamps and SRT, with a per-player support matrix. - [Train/Test Split with Stratification](https://elysiatools.com/en/tools/train-test-split-with-stratification): Class-stratified train/validation/test split or stratified k-fold for CSV/JSON datasets — seeded, reproducible, with distribution reports, leakage checks, SMOTE preview and CSV export. - [Text Encoding Forensics and Repair](https://elysiatools.com/en/tools/text-encoding-forensics-and-repair): Inspect text encoding, BOM, newline style and mojibake symptoms, then produce a scored local repair candidate. - [Chat Transcript to PDF](https://elysiatools.com/en/tools/chat-transcript-to-pdf): Lay out multi-role chat transcripts into a PDF conversation ## Samples - [PDF Samples](https://elysiatools.com/en/samples/pdf-samples): Generated PDF samples from tools dated 2026-02-01 to 2026-02-10 - [Distributed Tracing Samples](https://elysiatools.com/en/samples/distributed-tracing-samples): Comprehensive distributed tracing examples using Jaeger, OpenTelemetry, and other modern observability tools for microservices architecture - [JWT Samples](https://elysiatools.com/en/samples/jwt-samples): Comprehensive JWT examples from basic token structure to advanced security implementations - [WebRTC Real-Time Communication Samples](https://elysiatools.com/en/samples/webrtc-samples): Comprehensive WebRTC samples for peer-to-peer audio/video communication, data channels, screen sharing, and signaling server implementation
