This guide shows exactly how to use the CSV Column Extractor from start to finish: what to prepare before you open it, which settings actually change the result, how to read the first draft, and how to turn it into something you can publish or send. Expect to produce something usable within your first five minutes.
What to Have Ready First
- The goal. One sentence describing the exact result you need.
- The raw material. CSV text plus the names or positions of the columns to keep..
- The constraints. Length, tone, format and where the result will be used.
Step 1: Describe the Job in Plain Language
Open the CSV Column Extractor and write two or three sentences that cover the task and the person it is for. In practice CSV Column Extractor is a data selection tool that reads a CSV and outputs only the columns you choose, in the order you choose them. Specific inputs produce specific outputs; vague inputs produce generic results you end up rewriting from scratch.
Step 2: Set the Options That Change the Result
Scan the settings once and change only what your task needs. Change one setting, generate again, and compare - changing three settings at once teaches you nothing about which one helped. If you are unsure, keep the defaults for the first run.
Step 3: Generate and Read Before You Edit
Read the entire result once before touching a sentence. Note where it is strong and where it wanders. Editing paragraph one while paragraph three still needs cutting means you will write paragraph one twice.
Step 4: Edit for Truth and Voice
- Replace generic lines with one real number, name or example only you know.
- Rewrite the opening sentence - it decides the voice of everything after it.
- Verify every fact, date, price and link before the result goes anywhere.
Step 5: Copy, Verify and Save the Prompt
Copy the finished result into your document, editor or campaign, then paste the prompt that worked into a note you control. Two weeks of saved prompts become a personal library that makes every future run faster.
Worked Example
Input: name,age,city,email\nAda,36,London,ada@x.com\nKeep: name, email
name,email\nAda,ada@x.com
The same five steps applied to real input: brief, options, generate, edit, save.
Five Habits That Make You Faster
- One goal per generation instead of stacking three requests.
- Keep a running file of prompts that produced keepers.
- Change one variable at a time so learning compounds.
- Regenerate the weak section rather than the whole result.
- Spend the saved time on the edit only a human can do.
When the First Result Disappoints
- Too generic - add the audience, a number and one unique detail.
- Off target - restate the goal in the first line of your input.
- Too long or too short - set an explicit length instead of hoping.
- Still wrong - split the job into two smaller runs and merge the best parts.
Frequently Asked Questions
Can I reorder columns as well?
Yes - the output order follows the order you list the columns in.
Does it keep the header row?
Yes, headers are included by default so the result stays a valid CSV.
What about quoted fields containing commas?
Standard quoted CSV is respected throughout extraction.
Is my file stored?
No - extraction happens locally in your browser.
