How do I convert my .xlsx file to CSV?
Drop your file here, or choose it to preview its columns and rows in this browser. Nothing is uploaded. Review the table, then download CSV. See the download limits below.

What does a .xlsx file contain?
An .xlsx spreadsheet packages workbook and worksheet parts. xmetric imports its first worksheet as a table, rather than editing Excel formulas or formatting.
Format source: Microsoft Excel XLSX format documentation. The source describes the format; xmetric-specific behavior is stated separately.
How does Microsoft Excel XLSX compare with CSV?
Choose a format for the information you need to retain. A flat table cannot preserve a report layout, spreadsheet formatting or every source type.
| Format | Structure | Type or compatibility consideration |
|---|---|---|
| Microsoft Excel XLSX | Workbook containing worksheets | Imported cell values |
| CSV | Delimited text rows | Inferred on import; no stored schema |
Sources: Microsoft Excel XLSX format documentation; CSV documentation.
What should I check before using my .xlsx result?
Exports are limited to 100,000 rows. Check the preview and inferred column types before downloading. Only the first worksheet is imported; formulas and formatting are not preserved.
Compare column names, nulls and important values with your source before sharing a table or chart.
What limits apply to my data?
These limits apply to tabular imports, not native Power BI or Tableau report compatibility. File size and browser memory limit what xmetric can open. Table downloads reject oversized results instead of silently dropping rows.
| Limit | Current behavior |
|---|---|
| File size | 32 MiB on constrained devices; 160 MiB otherwise |
| Imported rows | Up to 3,500,000 |
| Preview page | 100 rows |
| Download | All rows, up to 100,000 rows; no sampling |

Can I open my .xlsx file without uploading my data?
Yes. xmetric processes the selected local file in your browser. Opening the file does not upload it; saving a workbook online is a separate action.
What should I check after importing .xlsx?
Move the intended table to the first worksheet and check headers and dates.
Does the CSV download include every row?
Yes, within the 100,000-row download limit. Larger downloads are rejected; the converter does not return a silently sampled file.
