Privacy note
Your input is processed locally in your browser whenever possible. We do not store your data.
Flow
- Parse delimited rows into table structure.
- Map first row as optional headers.
- Render grid preview with row/column consistency checks.
Example
Worked example: inspect monthly report rows
- 1 Paste a tab-delimited report with headers.
- 2 Viewer renders a grid and highlights uneven rows.
- 3 Fix source data before exporting downstream.
You can verify structure quality before conversion.
How
- Paste table-like content into the input panel.
- Run viewer mode to render row/column preview.
- Check headers and data quality before next conversion step.
Cases
- Spot malformed rows before CSV/JSON conversion.
- Review imported exports from third-party systems.
- Validate header naming and value consistency.
Avoid
- Assuming viewer validates business rules, not just table structure.
- Pasting inconsistent delimiter formats across rows.
- Treating empty cells as parser failures.
FAQ
Does excel viewer send my input to a server?
No. Excel Viewer handles the input in your browser whenever possible, so routine conversions, previews, and copy actions stay on your device instead of being sent to Calctrove servers.
Can I view tab-delimited data too?
Yes, tab-delimited table content is supported in viewer workflows.
Why do some rows show missing columns?
The source likely has inconsistent delimiters or unescaped separators.
