Inspector-supported workspace

Trend Detection can work with structured samples, and the sidebar inspector can profile a bounded preview without uploading your data.

Preview analysisColumn-awareClient-side

Use the inspector for quick row, column, missing-value, duplicate, type, and quality signals.
For large files, the inspector analyzes a capped preview so memory use stays predictable.
Use related tools to continue into cleaning, validation, conversion, or reporting workflows.

The inspector is a lightweight preview helper; the main tool remains responsible for the full transformation or export.

What is Trend Detection?

Trend Detection Analyzer is a free, browser-based tool that helps you understand a dataset at a glance. Surface monotonic trends, level-shifts, and seasonality in time series. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.

How to use Trend Detection

1Paste your data or drop a file (CSV or JSON).
2Read the generated summary — types, counts, distributions, and any issues found.
3Export the report, or send the data to another tool to act on the findings.

Features

Per-column types, nulls, uniques, and stats
Spot data-quality issues fast
100% client-side — no upload, fully private
Free with no account, no watermark, and no daily limit
Works on large inputs, limited only by your device's memory
Load a sample, then copy, download, or share your result

Common uses

Profiling an unfamiliar dataset before analysis
Quick one-off analyzer jobs without opening a heavy app
Preparing data before importing it elsewhere
Sharing a reproducible result with a teammate via a link

Used by

Data analysts
Researchers
Business analysts

Analysts

Common errors

A summary is treated as proof that the dataset is clean.
Outliers are removed automatically without checking whether they are real events.
Column types are trusted without reviewing mixed or sparse fields.
Duplicate or missing-value issues are ignored before visualization.

How it works

1Profiles the data input.
2Computes counts, inferred types, summaries, and warnings where supported.
3Turns findings into a practical next step.

Recommended workflow

1
Prepare the input
Profile the data first so missing values, types, duplicates, and outliers are visible before you edit it.
2
Run Trend Detection
Review the preview, copy or download the result, and keep everything local in your browser.
