Huawei Counter Parser
Load a Huawei PM counter CSV / TSV export. Get per-column stats, sortable cell tables, outlier flags, and a top/bottom-5 ranker for any KPI.
Huawei U2020, MAE-NCE, and iManager all export performance management (PM) data as delimited CSV or TSV — one row per cell, one column per counter. Counters use names like L.E-RAB.AbnormRel.RadioExpiry, L.Traffic.ActiveUser.DL.Avg, or L.HHO.ExecSuccOut. Dropping these exports into Excel works, but spotting the three cells killing your handover success rate across 5 000 rows takes too long. This free online Huawei counter parser auto-detects the delimiter, computes per-column min / max / mean / median / standard deviation, flags statistical outliers (|z| > 2), and lets you instantly rank cells by any numeric column. Everything runs in your browser — no uploads, no logs, no cloud — so you can safely use it with production PM exports. Typical users are Huawei RAN performance engineers, RF optimisers, NPO analysts, and audit teams.

Frequently Asked Questions
Which Huawei export formats does it accept?
Any comma- or tab-separated text export from U2020, MAE-NCE, iManager, or a direct query result. The tool auto-detects the delimiter, trims whitespace, and strips BOM characters.
Is my performance data uploaded anywhere?
No. All parsing happens locally in JavaScript using the browser FileReader API. Nothing is sent over the network after the tool page itself has loaded.
How are outliers detected?
For each numeric column the tool computes mean and population standard deviation; any cell with |value − mean| > 2σ is marked as an outlier. This is a simple rule that catches most genuinely bad cells without over-flagging.
Can I export just the outlier cells?
Yes — use the search box to filter the cell list, then click "Export filtered CSV". Only the visible rows are written.
How It Works
The parser auto-detects whether the delimiter is a comma or a tab by counting the first header line. Values that parse as finite numbers are treated as numeric; everything else becomes a string column.
- Per-column stats: count, min, max, mean, median, standard deviation.
- Outliers are cells whose value is more than 2 standard deviations from the mean.
- Pick any numeric column to see the top-5 and bottom-5 cells.
- Export the currently filtered table as CSV.
