How do I open my .jsonl file?
Drop your file here, or choose it to preview its columns and rows in this browser. Nothing is uploaded.
Paste your own data, edit it, then import it again to update the table. Example data uses the separate button below.
Choose a file to begin.
What does a .jsonl file contain?
JSONL and NDJSON store a JSON value on each line. This importer requires a flat object on each nonempty line.
Format source: JSONL / NDJSON format documentation. The source describes the format; xmetric-specific behavior is stated separately.
How does JSONL / NDJSON 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 |
|---|---|---|
| JSONL / NDJSON | A flat JSON object on each line | JSON scalar values |
| CSV | Delimited text rows | Inferred on import; no stored schema |
Sources: JSONL / NDJSON format documentation; CSV documentation.
What should I check before using my .jsonl result?
Each nonblank line must be a valid flat JSON object. Nested structures need flattening first.
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 .jsonl 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 .jsonl?
Do not wrap JSONL in an outer array; check the line named in a parse error.
Can I turn this table into a chart?
Yes. After checking the table, choose Chart in xmetric to continue with the imported data. Text formats may be converted to CSV for that handoff; review inferred types and download limits.
Which other formats can I convert my .jsonl file to?
Choose a supported conversion below to review the table before downloading another format.
