Quick use cases
File structure overview
- One sheet named Worksheet per file
- Nine typed columns starting at row 1 headers
- Dense tabular rows (no charts, pivots, or macros)
- Size variants scale row count, not schema
Sheet: Worksheet
A1: ID | B1: Name | C1: Email | D1: Phone | E1: City | F1: Country | G1: Score | H1: Date | I1: Notes
A2: 1 | B2: sample name | C2: user@example.com | …Integration notes
Who uses this format
Common integrations
Common validation issues
- Date format interpretation changes across locales
- Mixed string/number cells after re-save in Excel
- Hidden filters or wraps added by desktop Excel
- Timeouts when loading the largest variants in constrained browsers
Format compatibility and support
Compatibility
- Opens in Excel, Sheets, LibreOffice Calc, and common XLSX libraries
- Designed as plain tables—formatting extras are minimal
- Not a substitute for formula-heavy or multi-sheet templates
Import/export support
- Import: Excel, Sheets, BI connectors
- Export: office suites and reporting systems
- Conversion: XLSX to CSV, JSON, PDF
Why multiple sample file sizes exist
| Size | Typical use |
|---|---|
| 512KB | Quick sanity checks and smoke tests. |
| 1MB | Baseline import tests in local/dev tools. |
| 2MB | Common integration-scale test volume. |
| 5MB | Parser stress testing for medium datasets. |
| 10MB | Performance benchmarking for Excel upload limits, sheet parsing, and converter performance. |
Format comparisons
XLSX vs CSV for test fixtures
- XLSX is better when your pipeline expects an actual .xlsx workbook and sheet picker behavior.
- CSV is easier to inspect and compare in Git; relative file size depends on the data.
These samples vs custom Excel templates
- Downloads here are size-scaled synthetic grids (ID through Notes)—not finance, inventory, or HR templates.
- Build formula-heavy or multi-sheet templates separately; use these files for parser, converter, and upload QA.
Practical guidance
Which Excel sample size should I download first?
Start with the 512KB workbook to verify headers and import mapping, then move to 1–2MB for typical integration volume, and use 5–10MB only when you need upload-limit or memory stress checks.
Using these files with ConversionTab converters
Upload a sample on XLSX → CSV, JSON, or PDF to confirm sheet selection, header detection, and output shape before testing with production workbooks.
Frequently asked questions
How do I use XLSX sample files for import testing?
Start with the 512KB file, confirm the nine header columns map to your importer, then scale up to larger variants to check timeouts and memory.
What is inside these Excel sample files?
Each download is a single Worksheet with columns ID, Name, Email, Phone, City, Country, Score, Date, and Notes filled with synthetic rows. Larger files have more rows of the same shape.
Are XLSX files better than CSV for templates?
For multi-sheet workbooks, formulas, and formatting, yes—build those separately. These samples are flat grids for size and parser testing; CSV is still lighter for simple machine exchange.
Why are multiple sample file sizes provided?
Different sizes help with smoke tests, parser validation, stress checks, and realistic performance benchmarking across import flows.
Can these samples be used in CI testing?
Yes. They are commonly used to validate parsers, import logic, and conversion reliability in automated pipelines.
How should I choose the right sample variant?
Pick small files for correctness checks and larger variants for performance and memory stress testing.
