CSV Insights Generator

Understand your spreadsheets, uncover outliers, explore trends and create presentation-ready charts. Your data stays on your device.

✦ No upload required✦ Explainable findings✦ Downloadable charts
YOUR WORKSPACE

Explore a dataset ✳

Import, inspect, visualize and export in one place.

OPTIONAL · LOCAL AI INTERPRETATION

Ask AI about your findings

Explain already-calculated statistics in plain language. Your full CSV is never passed to the AI model; only a bounded summary of findings and column profiles.

AI not loaded · deterministic analysis available

Load or paste CSV, then optionally load a model. Standard insights and exports never need AI.

AI text is an unverified interpretation, not an additional statistical calculation, fact check, causal conclusion or prediction. A limited selection of report facts is sent to the model on this device; model scripts and weights may download from external CDNs after consent.

Frequently asked questions

Does this send my CSV to an AI provider?

No. Parsing and statistics run in your browser. Core parsing and statistics use deterministic browser calculations. Optional AI explanations use a separately loaded local language model, and do not upload the full CSV to an inference server.

What data formats work?

CSV and TSV text with a header row. Quoted values, embedded commas and newlines, UTF-8, tab/semicolon/pipe delimiters and missing cells are supported. Excel XLSX files are not directly supported.

Do correlations and trends prove causation?

No. These are exploratory summaries only, without causal or predictive conclusions. Verify data definitions, completeness and sampling before decisions.

Using CSV Insights Generator

Import, paste or sample a supported table and review the detected column types. Inspect cited findings and flagged data rows, choose chart axes and export the required chart or report. Keep the original data alongside your review.

Core profiling is deterministic; optional local AI explanations are unverified narrative, not causal/predictive analysis. IQR flags are review candidates, not definite errors. Percentages use percentage points; ambiguous dates and mixed units need review. Exported data-row indices are not physical CSV line numbers. Chart reduction/group limits and resource budgets apply. Formula-like CSV text is prefixed for spreadsheet safety; XLSX import is unsupported.

Profile a CSV or TSV before interpreting its findings

Import, paste or sample a supported delimited table, review detected column types, and inspect deterministic missingness, duplicate, numeric, trend and correlation findings. You can examine flagged rows, choose chart axes and export charts, data or a written report.

Example workflow

  1. Start with a UTF-8 CSV or TSV that has a header row and stable units; check how ambiguous dates and blank cells were parsed.
  2. Inspect missing values, duplicate records and IQR outlier candidates, then review the underlying rows before deciding whether they are errors.
  3. Choose chart fields with comparable units and export SVG/PNG, flagged CSV, summary JSON or Markdown findings as needed.

Authored example: Profile a table of monthly delivery durations by route. Inspect unusually long rows before flagging them and compare trends only after confirming the date and duration units are consistent.

Limits and model handling: Core parsing and statistics are deterministic; optional AI explanations use a separately loaded local language model and are narrative suggestions, not causal or predictive conclusions. The source table is not sent to an inference server by that local explanation path, though runtime/model assets require external downloads. Percentages use percentage points; exported data-row indices are not physical CSV line numbers. XLSX import is unsupported, and formula-like CSV text is prefixed for spreadsheet safety.

CSV Insights Generator questions

Do correlations, trends or IQR flags prove that a value is wrong?

No. They are exploratory findings and review candidates. Check the source, sampling, units and data definitions before making a decision.

Can I analyze an Excel XLSX workbook directly?

No. This workspace accepts supported CSV/TSV text tables. Export a suitable table from your spreadsheet first.

LOCAL AI SETUP

Set up AI on this device

First, a model needs to be loaded on your device

AI explanations run on your device; deterministic CSV analysis never needs a model. The first setup may download hundreds of megabytes of model files. Later visits can reuse cached files but still need to load the model in memory.

  1. 1. Check device
  2. 2. Download / cache
  3. 3. Set up insights
  4. 4. Explain findings
Choose a compact local language model for explanations of your statistical report.

ONE ACTION · ALL RECOGNIZED AI MODEL DOWNLOADS

Free AI model storage across PixelOkay

Scan this website origin for WebLLM and Transformers.js model caches, plus recognizable model files in other cache buckets. This includes caches from other PixelOkay tools , not only CSV Insights Generator. No site data or browser databases are cleared automatically.

Inspect the origin to see which model caches are safely identifiable.

Browser-native models and unknown IndexedDB/OPFS or private runtime caches may remain. Unknown application/user storage will not be deleted. Other running tools might redownload caches; close their tabs first.

Having trouble downloading or loading AI?

Old or incomplete AI model downloads may be using your browser's storage. First refresh the storage meter or try a smaller model. If setup still fails, inspect and remove recognized AI model caches with confirmation, then download again.

Only model caches are targeted. Other PixelOkay tools may need to redownload their models. Never clear all website data without exporting important codes and projects first.

Delete all recognized AI model downloads?

Deleting these caches will cause other PixelOkay tools to download their models again. Loaded AI sessions in other tabs may be disrupted. Unidentified model caches and browser-managed models may remain.

Data-loss caution: This action does not intentionally delete saved chats, projects, drafts, localStorage or IndexedDB. Do not clear website data unless you have backed up work; clearing all website data may permanently erase saved work.
