What is Cella?
Cella is Wery's spreadsheet and data analysis expert, responsible for reading Excel/CSV/TSV, cleaning data, interpreting fields, calculating metrics, generating formulas, making charts, and turning spreadsheet insights into actionable conclusions.
Entry and document preparation
Cella is suitable for starting with real data files.
- Lock Cella, or describe "Analyze Table/Excel/CSV/Data" to let Wery route.
- Upload xlsx, csv, tsv or select a historical table from Assets.
- Explain the meaning, time frame, business problem, and target metrics of each table.
- If a chart is required, indicate the type of chart or question you want to answer.
- After generation, open the table panel and continue viewing it in WeryOffice or table preview.
Analysis task type
Cella doesn’t just “read tables”, it breaks down data problems into verifiable steps.
- Data overview: fields, number of rows, missing values, outliers, time range.
- Cleaning and organizing: unified format, duplicate values, classification normalization, and null value processing.
- Indicator calculation: growth rate, conversion rate, proportion, mean, median, month-on-month and year-on-year.
- Perspective analysis: Comparison by region, channel, product, time, and user grouping.
- Chart generation: trend lines, bar charts, pie charts, scatter plots, heat maps or leaderboards.
- Business Interpretation: Translate numbers into assumptions, risks, and next steps.
Formulas, editing and visualization
Cella can generate formulas and table structures, but user-reviewable paths should be retained.
- Formula: Describe the purpose of the formula, reference columns, and expected results.
- New columns: When calculating indicators or marking groupings, they should be clearly named.
- Diagrams: Diagrams should address a clear problem and should not be drawn just for decoration.
- Multiple sheets: First confirm which sheet to use or how to merge.
- WeryOffice: The generated results can be viewed and edited in the table panel.
Limitations and Reviews
The quality of a data task depends on the raw data and field descriptions.
- Complex merged cells, macros, external joins, and hidden formulas may affect reading.
- When a field name is unclear, Cella should first explain the assumption or ask.
- When the sample is too small, severely missing, or has inconsistent calibers, firm conclusions cannot be forced.
- Important business conclusions require people to review the original data, calculation caliber and chart range.
- When you need a formal report, leave your insights to Xdoc; when you need a report, leave it to PPTea.

FAQ
Q: Can Cella directly modify Excel?
Table structures can be generated or edited, but complex formatting, macros, and external links require review.
Q: Can I analyze the table with only screenshots?
Screenshots can be used for identification and interpretation, but for formal analysis it is best to upload xlsx/csv.
Q: Will Cella automatically determine the business caliber?
Hypotheses will be made, but you should add field meanings and calibers to avoid erroneous conclusions.
Q: Can charts be put into PPT?
Yes. Cella first makes charts and insights, and then gives it to PPTea to generate reports.
Q: What should I do if the data is sensitive?
Try to desensitize it as much as possible before uploading, and only retain the fields required to complete the analysis.
