Sampling methods
Choose the sampling design that matches your data.
Sample Wizard supports common probability sampling workflows used in audits, surveys, research, monitoring, and operations.
Systematic sampling
Pick records at a calculated interval after a random start for repeatable audit and quality-control workflows.
Stratified sampling
Sample inside selected groups so regions, teams, categories, or segments stay represented in the final output.
Cluster sampling
Select complete clusters when field logistics require sampling by area, school, facility, branch, or other groups.

Prepare your Excel file
Keep one header row, avoid merged cells, and make sure the column used for strata or clusters is filled consistently.
Choose clear sample rules
Define the confidence level, margin of error, population size, sampling method, and any grouping column before exporting results.
Document the output
Keep the sample summary with your exported rows so reviewers understand how the sample was generated.
FAQ
Questions people ask before using an Excel sampling tool.
Can I select a random sample from Excel without formulas?
Yes. Upload the spreadsheet, choose simple random sampling, and Sample Wizard generates the selected rows without requiring Excel formulas or manual sorting.
When should I use stratified sampling?
Use stratified sampling when your dataset has important groups, such as governorate, gender, product category, branch, or team, and you want the sample to keep those groups represented.
How does the sample size recommendation work?
The tool estimates a recommended sample size from the population size, confidence level, and margin of error, then applies finite population correction for bounded Excel datasets.
Can I export the result back to Excel?
Yes. After generating the sample, you can download the selected records and operational assignment files as Excel outputs.
