URL: https://docs.valsight.ai/create-upload-tables/
Description: There are important Naming Guidelines to follow when choosing worksheet and column names.
The default way to upload your data into Valsight are regular tables. These tables are organized like a classic relational table.

*Important: Follow the [Naming Guidelines](/naming-guidelines/) when choosing worksheet and column names.*

These tables can contain zero or more levels, they are the most flexible way to upload data.

Some examples:

A table with no dimensional information, not even time:

| Measure |
| ------- |
| 10      |

A table that contains one numeric value per year:

| Year | Inflation |
| ---- | --------- |
| 2018 | 2%        |
| 2019 | 3%        |

A table that contains multiple numeric values per year:

| Year | Inflation | InterestRate |
| ---- | --------- | ------------ |
| 2018 | 2%        | 4%           |
| 2019 | 3%        | 5%           |

A table that contains two levels and multiple values

| Year | Country | Inflation | InterestRate |
| ---- | ------- | --------- | ------------ |
| 2018 | DE      | 2%        | 4%           |
| 2019 | DE      | 3%        | 5%           |
| 2018 | US      | 4%        | 2%           |
| 2019 | US      | 2%        | 3%           |
