Export SQL Results to CSV and Excel Safely
A technical how-to showing how to export SQL query results to CSV or XLSX without corrupting values (leading zeros, accented characters, dates). The author demonstrates that CSV exports preserve bytes but that damage usually occurs when Excel guesses column types on open. Recommended practices include opening CSVs in Excel via Data → Get Data → From Text/CSV (set File Origin to UTF-8 and mark code columns as Text), adding a UTF-8 byte order mark (BOM) on export (e.g., sqlite3 .once --bom) to avoid accent issues, and generating real .xlsx files (e.g., with pandas.to_excel) when humans will double-click the file. The article also lists quick checks to run after export (row counts, code endpoints, an accent, a date) and details other common CSV pitfalls.
- The author tested exports on 2026-08-08 using SQLite 3.51.1 and inspected files byte-by-byte to show exports themselves are correct.
- Opening a CSV by double-clicking in Excel can silently change data types (e.g., drop leading zeros or mis-interpret character encoding), while importing via Data → Get Data → From Text/CSV lets the user set types and encoding.
- Adding a UTF-8 byte order mark (BOM) at file start (sqlite3 .once --bom results.csv) signals encoding to Excel and prevents accented-character corruption.

Five Checks to Validate AI-Generated SQL
This technical guide explains five quick checks to verify results produced by AI-generated SQL queries. It warns that a running query only proves syntactic correctness and outlines practical tests: (1) compare row counts before and after joins to detect fan-out, (2) watch for NULLs breaking NOT IN filters (use NOT EXISTS), (3) ensure filters sit in WHERE vs HAVING appropriately, (4) confirm the denominator used by averages or percentages, and (5) ask the AI to read the query back clause-by-clause. The author cites the BIRD benchmark (Li et al., 2023) showing large gaps between model and human execution accuracy and provides examples and remediation patterns to avoid incorrect analytics numbers.
- The article provides five checks to validate AI-generated SQL before trusting numeric results.
- Check 1: count rows before and after each JOIN to detect fan-out that inflates SUM/AVG values.
- Check 2: NOT IN fails if the lookup contains NULL; use NOT EXISTS or clean the lookup table instead.

How to Build a Tableau Dashboard and Story
Step-by-step tutorial showing how to create a published Tableau dashboard and a three-point narrative story from a real dataset. The guide uses the Telco Customer Churn dataset (7,043 customers) and a public GitHub repo for data-shaping code. It stresses shaping data upstream (one row per entity, 1/0 outcome column, readable names, ordered buckets), creating a single calculated field for rates (Churn Rate = AVG([Churned])), building four focused worksheets (one point each), assembling them into a dashboard, and sequencing three story points (problem, mechanism, action). It explains Tableau Public publishing requirements (workbooks must use extracts) and gives practical UI steps and common error fixes. The guide also covers visual rules (one-accent color, bar chart accuracy) and advises documenting limitations when publishing.
- Worked example uses the Telco Customer Churn dataset on Kaggle with 7,043 customers (one row per customer).
- Author provides a public GitHub repository (telco-churn-analysis) containing the Python script that shapes the data for the example.
- Recommended calculated field for the rate: Churn Rate = AVG([Churned]) (1/0 column average).

Build Text Summarizer with Hugging Face
This tutorial explains how to build a text summarizer using the Hugging Face Transformers library and its high-level pipeline API. It shows installing transformers and torch, initializing a summarization pipeline (example: facebook/bart-large-cnn), and controlling outputs with parameters such as max_length, min_length, and do_sample. The guide covers handling long documents via chunking and recursive summarization, and notes optional fine-tuning using Hugging Face's Seq2SeqTrainer with evaluation by ROUGE for domain-specific needs. Example Python code is provided for quick local inference and file-based workflows.
- The guide demonstrates building a summarizer using Hugging Face Transformers' pipeline API.
- Recommends facebook/bart-large-cnn as a robust out-of-the-box summarization model.
- Requires the transformers and torch (PyTorch) libraries; installation via pip is shown.
