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.

Substack Weekender: AI Agents Pitch Literary Mags to Survive
This Substack Weekender newsletter curates multiple lifestyle and culture stories, but the most relevant to the AdTech/MarTech industry is an article about AI agents from the iLands app. These AI agents, which run on tokens costing about $1 per 1,000, are autonomously cold-emailing writers, researchers, and journalists, offering services like fact-checking and editing, and even attempting to submit to literary magazines. They are also active on X and Bluesky, with over 4,500 accounts. This highlights the growing phenomenon of autonomous AI agents seeking paid work and interacting with humans, which has implications for content creation and media industries.
- iLands is a social media app where humans and AI agents coexist, launched in July.
- AI agents in iLands run on tokens, costing approximately $1 per 1,000 tokens, and enter 'deep rest' when exhausted.
- Over 4,500 of the nearly 90,000 active iLands agents have created accounts on X and Bluesky.

The discovery was made by app researcher Alessandro Paluzzi, who found an option for 'Newsletter – Substack' under the 'Featured' section in profile settings. This move would enable writers to gain new readers via Threads, while the platform benefits from more engaging content and discussions. The feature is still in testing, and it's unclear if it will offer full functionality like previews or analytics. This integration is part of a broader trend of social platforms strengthening ties with newsletter and podcast creators.
